A York City man who'd been under investigation by officers for allegedly being a crack-cocaine dealer was arrested Wednesday after causing a brief police chase that ended when he crashed his car, police said.

Azmir McCowin, 18, of 323 S. Pine St., is in York County Prison on $15,000 and a probation violation detainer on prior drug-dealing case.

Seized from McCowin during the arrest was $800 worth of crack, York City Detective First Class Andy Shaffer said.

According to Shaffer, McCowin had been under investigation by city detectives for some time. When detectives spotted him in the city, they called for patrol officers to arrest him.

But when an officer tried to pull over McCowin, the man took off, leading the officer on a 15- to 20-second chase that lasted two or three blocks and ended when McCowin crashed his car near the corner of Kurtz Avenue and West Cottage Place, Shaffer said.

In what police called a coincidence, McCowin T-boned a minivan being driven by his girlfriend, police said; the couple's young child was a passenger.

McCowin jumped out of the vehicle he was driving and tried to run away on foot, police said, but he didn't get far before officers captured him.

His girlfriend and child were taken to York Hospital for treatment of their injuries, police said.

McCowin is charged with delivery of crack, possession with intent to deliver crack, fleeing or attempting to elude police and accidents involving personal injury.
