Disturbing moment man is caught URINATING on a parked car outside a church before slashing 66-year-old man's throat when he told him to stop: Victim is clinging to life

An elderly man had his throat slashed with a boxcutter after he asked a man not to urinate on a car outside a church.

The 66-year-old was rushed to hospital after he and a security guard approached the man on New York City's Lower East Side about 5pm on Sunday.

The victim was a churchgoer at Immaculate Conception Church, and spotted the man about to urinate on an employee's car, police said.

Not pleased to be told off, the man argued with the pair before taking out the boxcutter and slashing the victim's throat, then fled.

Surveillance photos released by police showed the suspect wearing an orange and black puffer jacket with a hood, and a grey beanie holding a drink and dragging a cart

The East Village resident was rushed to Mount Sinai Beth Israel Hospital in critical but stable condition with a 'severe' wound. The security guard was not injured.

Police said the victim and the man who wounded him have longstanding animosity and the attacker appeared to have mental health issues.

He was often seen pushing a cart outside a nearby McDonald's, which he was caught on CCTV dragging.

Other surveillance photos released by police showed the suspect wearing an orange and black puffer jacket with a hood, and a grey beanie holding a drink.

Anyone with information about the attack or who has seen the suspect should contact the NYPD.
