Dashboard camera footage has been released showing a suspect high on PCP being shot 45 times when he opened fire on police, after leading them on a four city chase.

Antoquan Watson, 27, of Williamstown, New Jersey, died after the shootout with cops in Atlantic City in 2014.

The video has just been released following a New Jersey Supreme Court decision this month that ruled dash cam footage of all fatal shootings involving police should be made public. A grand jury declined to indict the seven officers involved in 2015.

The incident in 2014 after the cops were called out to reports of a man with a gun at a Pleasantville restaurant.

Watson fled, and officers chased his SUV through city streets and along highways as he ran red lights and swerved around other vehicles. He also fired a round at officers while driving, authorities said.

Dash cam footage shows Watson driving through a red light, and hitting another car in Atlantic City.

Watson fired back and continued firing at the officers as he calmly walked across the street, until he was hit and collapsed to the floor.

Seven officers - four from Pleasantville and three from Atlantic City - shot Watson more than 40 times, continuing to fire after he fell to the ground.

However, the condition of the slugs made it impossible to tell which officer fired the fatal shot.

An autopsy, conducted on March 28 and March 29, 2014, revealed that he sustained a total of 45 gunshot wounds.

It also revealed the existence of PCP in Watson’s system - a drug with hallucinatory and pain numbing properties that can appear to give users almost superhuman strength or resistance to pain.

Police reports reveals that officers believed Watson was wearing a bulletproof jacket because of the way he reacted to the bullets.

A grand jury reviewed the shooting and found the officers' actions were justified.

The release of the almost 13-minute video followed a decision by the state's top court in a case that was widely watched by government transparency advocates. That decision stemmed from another fatal police shooting in 2014 that occurred in Lyndhurst.

The justices ruled the town should have released video and use-of-force reports after a request from the North Jersey Media Group, following the shooting after a high-speed chase involving a stolen car.

They said dashboard footage can 'inform the public's strong interest' in the fatal police shooting without 'undermining the integrity of an investigation.'

The court agreed some other investigative reports from the shooting - which a grand jury determined was justified - did not need to be released.
