Pro-democracy protests in Hong Kong descended into chaos Sunday after a man attacked a local politician, biting off part of his ear.

Broadcaster RTHK reported that the victim was district councilor Andrew Chiu.

Video shows a man in a grey shirt wrapping his arms around Chiu’s neck before biting his ear while onlookers pummeled him and tried to end the attack. The attacker was then mercilessly beaten by onlookers on the ground until his head was covered in blood.

Another video shows the attacker standing with blood on his face, as onlookers throw trashcans and punches at him.

Following the attack, a video showed a stupified Chiu bleeding profusely, placing part of his ear in a plastic bag.

Local unverified reports said the man wounded five people with a knife as well. Two people are in critical condition. A kitchen knife was present at the scene, according to Reuters. According to the BBC, citing local reports, the man targeted protesters following a confrontation with a couple at the demonstration.

The disturbing scene took place at a mall called Cityplaza in the Hong Kong suburb Taikoo Shing after police confronted a group of protesters that had stormed the complex, using pepper spray and making at least one arrest of a journalist.

Mall protests reportedly occurred in other districts as well following larger pro-democracy protests on Saturday.
