Hong Kong wrapped up a weekend of tumultuous protests that resulted in 86 people — including one as young as 12 — arrested and a stern warning from the government.

“The escalating illegal and violent acts of radical protesters are not only outrageous, they also push Hong Kong to the verge of a very dangerous situation,” the government said in a statement.

Over the course of two days, police fired water cannons, 215 rounds of tear gas and even a warning gunshot after six officers drew their weapons in a bid to stem the unrest.

Protesters tossed bricks and Molotov cocktails at the officers, 21 of whom were injured in the weekend mayhem.

In total, 86 people were arrested, ranging in age from 12 to 52. They were slapped with charges including unlawful assembly, possession of offensive weapons and assaulting police officers.

The pro-democracy protests — now in their 12th week — erupted over opposition to a since-suspended extradition bill, which would have enabled the country’s criminal suspects to be extradited to mainland China for trial.

The demonstrations, which had been largely peaceful, have morphed into a broader call for more democracy in the Chinese-ruled territory.

More protests are slated for the week ahead — including a Wednesday rally at the headquarters of Hong Kong’s Cathay Pacific Airway. China has demanded the corporation suspend its staff involved in or who have supported the anti-government protests.

Meanwhile, Hong Kong lawmakers are pointing fingers at each other over who’s to blame for the weekend clashes.

Starry Lee, a pro-government member of the Legislative Council, decried the violence carried out by the protesters.

“You can say a lot of different opinions to the government,” said Lee, chairwoman of the Democratic Alliance for the Betterment and Progress of Hong Kong. “But violence is different. If we can accept violence, our city will be ruined.”

Kwok Ka-Ki, a pro-democracy legislator and member of the Civic Party, said Hong Kong leader Carrie Lam is to blame for the unrest.
