Philadelphia police arrested two men and were looking Sunday for two others who allegedly robbed more than a dozen teens at gunpoint at a Roxborough playground Saturday night, investigators said.

Officers nabbed 20-year-old Keith Washington and 24-year-old Linwood Stinson, both of Philadelphia, minutes after the 11 p.m. robbery outside the Kendrick Recreation Center at 5822 Ridge Ave., according to police spokesman Lt. Frank Vanore.

Vanore said the victims, who were not identified, were clustered in groups at the playground when a red Chevrolet Camaro pulled up. Three men got out of the car, approached the teens, and asked them whether any had marijuana. All said no.

Two of the men suddenly pulled out handguns and started pointing them at everyone in the group, Vanore said.

The robbers ordered the teens to lie on the ground and took their cell phones, cash, wallets, and other items, then drove off.

Minutes later, officers in an unmarked car spotted the Camaro at a stoplight at Henry and Allegheny Avenues. Police then converged on the car at 27th Street and Allegheny Avenue.

The three passengers fled. The driver, Washington, of the 2900 block of North 12th Street, was captured. Stinson was nabbed blocks away after a foot chase, according to Vanore.

The two other men are being sought.

Police recovered two BB guns and some of the stolen items, Vanore said. Officers also determined that the car had been stolen late last week.

Charges were pending.
