NIGHT OF TERROR! 250 pound naked man’s drug crazed rampage – bites a chunk out of teen’s face, displays super-human strength and then is shot dead by cops. WARNING! GRAPHIC CONTENT VIDEO!

Cellphone video released by WPTV Florida shows the chilling moment a 6-foot 250-pound naked man wennt on a one-man riot was shot dead by police officers after a barrage of Tasers failed to knock him out.

Delray Beach\Florida resident Robert Friskney was trying to get into his home Tuesday night when he saw the entrance blocked. Cops were battling nude berserker Anesson Joseph, 28.

Friskney told the TV station that Joseph was acting like an man-animal — hissing, growling as he lunged at the cops. As the naked hulk leapt viciously at the stunned police officers, they fired Tasers.

Sheriff's deputies told media  he appeared to be in a drug-induced “state of psychosis” AND as he continued to battle law enforcement they had no choice but to shoot him – dead.

Joseph’s alleged night of mayhem began with him terrorizing the suburban neighborhood called The Colony.

Cops say Joseph viciously attacked three people – a retired NYC cop, an 18 year-old and a ten year old boy.

Former NYPD officer Douglas Kozlik, 66, was  on his nightly walk when the naked 250 pound Joseph appeared out of the nowhere screaming and then chased the ex-cop down the street.

Tony Grein, 18,  had a box cutter on him and tried to defend himself with the sharp object.

According to Palm Beach County Sheriff Ric Bradshaw, the box cutter was of no use against the man mountain of terror  who seemed to have “'superhuman strength”.

In the battle, the drug-crazed Joseph bit and clawed at Grein’s face, trying to rip huge chunks of flesh  — attempting to eat Grein’s face.

“He's obviously delirious on something,” Palm Beach County Sheriff Ric Bradshaw said. “He is a huge guy. He takes a fighting stance. They're trying to get him on the ground. He starts charging them. The Taser did not affect him.”'

A battery of cop cars arrived on the scene and deputies shot the assailant with a Taser but it didn't faze him.

"The man then charged our deputy, and he discharged his firearm," a police spokesperson said. “'But he was not incapacitated. He was then Tased, but that also had no effect."

That’s when a sergeant fired three times with his revolver – one shot to the torso and twice on the lower part of the body, felling the rampaging juggernaut.

Law enforcement say they weren’t ‘sure if it was the gunshots or drugs that ultimately killed him. An autopsy is pending.

Robert Friskney who captured the harrowing standoff on his cell phone camera, says the deputies looked scared.

"There were no high fives from the cops," he told WPTV. “They didn't want to see this happen. They didn't want to see this end the way it did. It was very clear they were terrified."
