警方表示，晚上近10时，一批大约20人的自愿医疗人员由理大正门离开。晚上11时，一批大约10人的蒙面暴徒突然从理大正门跑出，防暴警察立即追截并将他们全部拘捕。
媒体报道，今晨6时许，还有4名暴徒试图突围，其中3人跑出数秒即被捉回，一人未跟随。
暴徒占据理大已一个多星期，其间警方多次呼吁理大内的人离开。由始至终，警方一直强调以“和平方式”及“灵活弹性”两大原则解决事件。警方在晚上继续通过让不同界别人士进入校园进行斡旋及劝说以解决问题。此外，警方亦曾协调红十字会与无国界医生进入理大施以适切的医疗协助。
香港警方呼吁现时仍留在理大的人，和平有序地离开，并承诺他们必定受到公平对待。

连日来，大量暴徒“占领”香港理工大学作为“基地”，香港警方自11月17日开始采取行动，将逾千名暴徒围困在理大中。
随着时间流逝，理工大学校园里开始缺水缺粮、满地垃圾，卫生情况恶化。暴徒不愿意被困，18日至少3次企图冲出校园，但却由于警方在外包围，撤离失败，多人逃跑不成反被拘捕。
香港特区政府和警方一直希望和平处理此事，警察公共关系科总警司郭嘉铨19日重申，警方不会实时拘捕自愿离开校园的未成年人士，会先拍照及登记资枓，但会保留追究权利，而成年人就会实时拘捕。
据警方此前数据，截至19日下午3时，共有1100人在理大校园附近被拘捕或登记，大部分都不是理大学生，其中600人属自愿离开。
另据港媒消息，截至20日清晨，仍有人滞留在理大校园内，6时许，4名暴徒试图突破警方防线，其中3人跑出公路后数秒即被警员发现并被拘捕，另一人并未跟随。#

Hong Kong (CNN) Last week, thousands of student protesters streamed into Hong Kong Polytechnic University and occupied the campus as the city's violent political unrest reached fever pitch.
Once inside, they soon faced an impossible choice: stay inside until supplies run out, or leave the university and risk getting tear gassed and arrested for rioting, a charge which can fetch a 10-year prison sentence.
Police accused protesters of turning PolyU and other universities into "weapons factories" that "look like military training grounds" and surrounded the campus.
Police have been on the edge of the campus for more than two days, firing round after round of tear gas at protesters who responded with makeshift petrol bombs, catapults and bows and arrows.

Hundreds of protesters were trapped, but some slowly managed to get out. Authorities said they had processed 1,100 people -- 600 of whom left willingly. Protesters were arrested if they were older than 18 or registered and then released if they were minors, police said.
By Tuesday morning, the violence had subsided and the campus was in ruins. Only a small number of demonstrators remain in the university.

Thousands of unused petrol bombs littered the campus on the path to the canteen, which had become something of a main headquarters for the protesters.
Only about 50 or so protesters were inside when CNN visited Tuesday morning. Some slept while others looked aimlessly at their phones.

He told CNN he arrived at the PolyU two days ago. But things had changed on Tuesday.

Fewer people were on the streets outside and the number of protesters inside were dwindling.
Protesters have been holed up at the PolyU campus since last week, after an escalation in the months-long unrest that saw multiple universities across the city fortified and turned into temporary protest camps. They had used the PolyU campus as a base from which they launched operations to block nearby roads and the Cross-Harbour Tunnel which connects Kowloon to Hong Kong Island.
By Tuesday, police had surrounded the school, and there didn't appear to be a way out. A handful of desperate protesters took to shimmying down a rope from a bridge and getting away on motorcycles.

The teen in the canteen said he had barely slept because of fears that police could storm the campus at any moment.
"I'm definitely very tired," he said. "I'm trying my best to look for a way out. Even though I know that the chance of (finding) a safe way out exists less and less by the second."
The teenager, like all those who spoke to CNN, declined to give his real name or have his photograph taken because he feared being identified and arrested by police.
❾ Items from a nearby library were piled up and used as barriers. | 图示占领者将从附近的图书馆的物品堆积起来，用作阻止警方行动的障碍。
Across the hall from the canteen, protesters had turned the gymnasium into a dormitory, despite the fact that an alarm was going off. Several people were still sleeping there at about 11:30 in the morning when CNN visited.

Back outside, groups of roving protesters looked for exits near the Jockey Club Innovation Tower, an impressive piece of architecture designed by Zaha Hadid. Several tried to jump across a highway near the pool, which had been emptied and used for Molotov cocktail-throwing practice. Protesters have justified this type of violence as proportional and meant to keep police at bay, but authorities say their actions are dangerous and potentially deadly.

One of those looking out was a surgeon who identified himself as Dr. Chiu. Chiu had come as part of a group of first aid volunteers two days earlier, and said he treated some pretty serious wounds -- lacerations deep enough to see the muscles, broken ribs and a fractured arm among them.

The less-experienced volunteers working with him struggled to cope at times. "I saw a lot of other first-aiders and other students, kids -- they're all crying," Chiu said.
He paused, took a deep breath and continued: He said had hoped that this generation of young people could have avoided this experience.
"They shouldn't bear this kind of responsibility."

But Chiu also said it was important to empathize with Hong Kong's police force, which has been criticized for alleged police brutality over the course of the city's almost six months of protests.
"They have been working under a lot of pressure these months," Chiu said.
Chiu then went off and looked for an exit. Trailing a few hundred meters behind were a group of three girls, including a 14-year-old who wouldn't give us her real name, but wanted to be called "Hannah."
Hannah said she came to defend not just PolyU, but the city and its freedom. She said she feels it's important for young people to fight for their freedoms and a democratic system.
"I know it's tough for everyone, and for us too. But faced with the authoritarian government, we can't be afraid. We have to go on," Hannah said.
⓯A Starbucks on the PolyU campus was heavily vandalized, as were others near the school. The coffee chain is regularly targeted by protesters because the family that owns Maxim's, which owns the Starbucks franchise in Hong Kong, has criticized protesters and supported police. | 图示香港理大校园内的一间星巴克（Starbucks）咖啡厅，像其他靠近理大的同牌子的咖啡厅一样，遭受严重破坏。这个咖啡连锁店成为香港示威者进行破坏的对象，是由于这个拥有美心饮食集团（Maxim）的家族，也拥有星巴克（Starbucks）的香港经营权，他们曾经批评示威者并支持警方。
Hannah explained that the situation hasn't been easy.
Like everyone else on campus during the protest occupation, sleep for Hannah has been hard to come by. She said Monday morning -- when police fired numerous rounds of tear gas in a bid to clear the campus -- was particularly tough, because they were not fully prepared for their encounter with police.
Hannah said she's a been a regular at protests since they began happening frequently back in June.
She usually is tasked with either neutralizing tear gas canisters fired by police or throwing them back at authorities.

"We have been here for over 48 hours now. It's very very tough for us, but we are worried that police might raid the campus. So we stay here and wait for rescue."
Hannah said that her mother was among the group of parents who had gathered near the university for a sit-in, requesting that police let the student-protesters inside the university leave without fear of arrest or harm.
