Hong Kong police on Thursday entered a ransacked university campus where authorities faced off for days with barricaded pro-democracy protesters, looking for petrol bombs and other dangerous materials left over from the occupation.
The Hong Kong Polytechnic University became the epicentre of the territory's increasingly violent protest movement when clashes broke out on November 17 between police and protesters armed with bows and arrows as well as Molotov cocktails.
The standoff settled into a tense stalemate during which hundreds fled the campus -- some making daring escapes, others caught and beaten by officers during failed breakouts -- leaving a dwindling core of holdouts surrounded by police cordons.
But in recent days, the last few people barricaded in the campus seemed to disappear.
University staff said they were only able to find a single protester on campus and reporters there struggled to see any major presence in the last 48 hours.
Late Wednesday, a lone masked man spoke to reporters inside the campus saying some 20 protesters remained.
But there was no sign of them on Thursday morning when police and firefighters moved in, 11 days after the siege began, for what was billed as an operation to secure dangerous objects now littering the once placid campus and to collect evidence.
Riot police in tactical gear began gathering dozens of discarded petrol bombs and bottles of chemicals that had been looted from the university laboratories.
Explosives experts went from room to room followed by a gaggle of reporters, passing walls daubed with graffiti insulting the city's police force and calling for greater freedoms under Chinese rule.
The university now faces a mammoth clean-up operation.
Swathes of the red-brick campus just a stone's throw from the city's famous harbour resemble an abandoned battleground covered in debris, barricades and the shattered bottles of Molotov cocktails.
A foul odour from rotting food in a canteen and overflowing garbage bins permeated parts of the campus.
On Wednesday, university leaders called for the police to end their siege and for the government to help with the disposal of dangerous materials.
Hong Kongers have protested in huge numbers over the last six months fuelled by years of growing fears that authoritarian China is stamping out the city's liberties.
Violence spiralled as Beijing and local leaders refused major concessions and the police were used to break up rallies on a daily basis.
Beijing and Hong Kong leader Carrie Lam have argued that a "silent majority" still supports the establishment and abhors the increased violence of radical protesters.
But that narrative was undermined by community-level council elections on Sunday which saw a landslide win for pro-democracy candidates across the city.
