A maniac in the Bronx attacked two people last month, breaking a woman’s arm with a metal pipe and assaulting a teenager in another incident, police said.

In the man’s first suspected attack, he targeted a 13-year-old boy, approaching him from behind and slamming the teen to the ground on Oct. 18 near Willis Avenue and East 144th Street in Mott Haven, police said.

The boy suffered minor injuries in the attack.

The fiend struck again last Saturday at about 3 p.m., beating a 58-year-old woman with a metal pipe near Walton Avenue and East 144th Street, cops said.

The woman was treated for her injuries at a nearby hospital.

Cops were asking the public to help them track down the suspect.
