PHILADELPHIA (CBS) - Police have arrested a West Philadelphia man they say shot and killed a teenaged basketball standout on Easter Sunday.

Police Commissioner Charles Ramsey says a tip call led authorities to the man they say shot and killed Jarell Seay, 18, on his front porch near 55th and Thompson on Easter Sunday.

“We got some information — I can’t go into too much detail without revealing the identity of the source — but we did get some information as to where he was located,” Ramsey said. “And U-S Marshals, along with our own warrant team, went out and got him.”

Ramsey says Julian Frisby, 21, was found hiding in the basement of a house in Norristown. He was arrested around 5:30 p.m.

Seay was a basketball standout at Wyncote Academy in Montgomery County (see related story).

Ramsey says detectives hope to learn more about a motive for the shooting after talking with Frisby.

In the meantime, detectives continue their search for a second man they say was with Frisby at the time of the shooting.
