In the span of eight days, two teenage females were grabbed off the street, dragged into an abandoned building and sexually assaulted near the corner of Grand Avenue and Kingsbridge Road.

Police say in both cases it was the work of one sexual predator. Last Thursday, police arrested Stephen Robinson, 48 and charged him with rape, criminal sex acts, sexual abuse and kidnapping.

On May 10, at around 2:30 in the afternoon on Kingsbridge Road, near Grand Avenue, police say Robinson grabbed an 18-year-old woman walking home. He allegedly forced her into a nearby abandoned building and tried to rape her.

Fortunately, the woman was able to escape prior to being raped and reported the incident to police.

A little more than a week later, on May 18, the same thing happened to a 17-year-old girl at the very same location, this time at around 11 p.m. And this time, the victim was raped.

According to police, Robinson lives on Morris Avenue, just three blocks from where both attacks occurred.

On Tuesday, the Daily News reported that last week, Bronx Homicide Detective Sean O’Toole identified a sketch of the rape suspect as Robinson, who O’Toole remembered arresting years before. That led to Robinson’s arrest for the recent assaults.
