Wild videos show a violent early morning street brawl in Brooklyn in which six people were injured and bloodied.

Footage from a doorbell camera and bystanders obtained exclusively by The Post shows a chaotic brawl spilling out of a Gerritsen Beach home into surrounding streets on Sunday, where at least one attacker lashed out with a knife.

Footage from a doorbell camera shows a thug in a dark shirt chasing another man, repeatedly making stabbing motions before apparently making his way through a group of people.

Police arrested 19-year-old Erick Caiza Iza and charged him with assault, menacing and possession of a weapon for his role in the brawl.

Video from a neighbor’s window shows a fight spreading from a house on Kane Street near Everett Avenue into the street.

“They were fighting, coming out into the street and continuing to fight until it got worse and worse. About 15 of them were pushing and headbutting each other,” the neighbor, who wished to remain anonymous, told the Post.

“Then they kicked and punched this one guy. I thought they were going to kill him.”

The videos available to The Post match the neighbor’s description of the violent fight.

At one point, when the brawl seems to be cooling down, a hooligan in a white T-shirt takes off his baseball cap and head-butts another man.

The two exchange blows until the thug in the white shirt is held down. However, his place as boxer is taken by another man in a white t-shirt who delivers a beating to the headbutted fighter.

The fight developed into a chaotic scrum that stretched across the entire street, with groups of fighters splitting off.

In the stabbing, which occurred at about 6:20 a.m., a 30-year-old woman and a 27-year-old man were injured in the face, a man in his 30s was stabbed in the neck and wrist, a 16-year-old received cuts to his arm and a 19-year-old man and a 29-year-old woman suffered cuts to their hands, police said.

All six were taken to hospital in stable condition, police said.
