Stranger beats 12-year-old NYC boy with crutch in random attack: video

An unhinged man randomly attacked a 12-year-old boy heading to school in Brooklyn — beating the youngster in the head with a crutch, shocking new video shows.

The boy was near the corner of St. Paul’s Place and St. Paul’s Court in Prospect Park last week when a stranger ran across the street and hit him twice with a single crutch, according to the NYPD and video they released early Wednesday.

As the maniac swung a third time, the pre-teen ran off, avoiding getting hit again.

Cops say the assailant picked the crutch up off the ground, possibly from a pile of trash, and was hanging out mid-block before he pounced on the unsuspecting kid. 

He mumbled something incomprehensible during the unprovoked Nov. 17 attack, cops said. 

The fiend calmly walked off after the assault, ditching the crutch on the sidewalk as he headed north on St. Paul’s Place. 

The victim suffered minor head injuries and was taken to a local urgent care in stable condition. He had been heading to the Church Avenue B and Q train station at the time of the attack.

The suspect was still on the loose Wednesday morning. 

He is described as a male with a dark complexion, a medium build and a beard. He was last seen wearing a black winter hat, a black jacket with a yellow hood, blue jeans and black sneakers.
