Petrol bombs, acid left on Yau Tsim Mong streetsLocal | Cindy Wan and Cissy So 20 Nov 2019
A large amount of petrol bombs and corrosive acid remained on the streets in Yau Tsim Mong after protests on Monday night.
Protesters turned up in the three districts in an attempt to rescue those inside Polytechnic University on Monday. About 100 protesters were arrested at the scene and 31 were sent to hospital.
Police officers of Yau Tsim Mong District also received multiple reports that a large amount of dangerous items, including corrosive fluid and petrol bombs, had been found on the street.
In Tsim Sha Tsui, citizens found boxes containing some 30 petrol bombs, bottles of medical-use alcohol and corrosive liquids near the junction of Carnarvon Road and Kimberley Road.
A restaurant on Temple Street in Yau Ma Tei also discovered a grey bucket of liquid suspected to be corrosive acid and reported to the police at 11.30 pm.
Police said they seized more than 3,900 petrol bombs at Chinese University of Hong Kong after receiving a report of criminal damage and arson from the school.
"If a person takes 10 seconds to hurl a petrol bomb, it will take 11 hours to throw all of them," said Kwok Ka-chuen, chief superintendent of Police Public Relations Branch at a press briefing yesterday.
About 100 liters of concentrated sulfuric acid, nitric acid and other dangerous chemicals also went missing from the school's laboratories, which can be used to make petrol bombs and other weapons that cause severe injuries, he said.
In other developments, a video circulating on the internet shows a white police van charging at the protesters' umbrella cordon line in Yau Ma Tei, prompting speculation that it led to a stampede.
Wong Wai-shun, senior superintendent of the Operations Wing, said it was "a tactical operation".
"Driving fast doesn't mean it's unsafe," he said, urging the public to trust the police.
Meanwhile, about 100 people occupied Pedder Street in Central at around 1pm to join the lunchtime protest.
A riot police officer was seen chatting with some people who asked about his British accent.
"I was brought up in the UK, but of course I was born in Hong Kong," he said. He compared the ongoing social movement to the Troubles in Northern Ireland.
