PHILADELPHIA (CBS) — Police say a man was knocked unconscious after he was punched by two people while at a charity basketball game in Olney.

Authorities say around 4:00 p.m. on Jan. 28, a 25-year-old man was at the charity game, at International Christian High School on the 400 block of East Tabor Road, when he was punched by an unknown man while he was sitting on the bench.

“During the game, at some point in time, there is probably an argument,” Philadelphia Police Lt. John Stanford told CBS 3’s Greg Argos.

Police say while the victim was being treated for injuries from the initial assault, a second suspect approached him and punched him a second time, knocking him unconscious.

Both suspects then fled the scene in an unknown direction.

Police say the victim was taken to Elkins Park, Albert Einstein Medical Center and treated for facial injuries.

The school’s principal says the purpose of the game was to raise money for a former student who is doing mission work in Guam.

It was open to the community and both the victim and the two suspects are not affiliated with the school.

“To turn something positive into something negative is something that doesn’t make any sense at all,” said Stanford.

Authorities describe the first suspect as a black male, in his late teens to early 20s. He was wearing a white t-shirt, black shorts, gray sneakers and was in the company of a female.

Police describe the second suspect as a black male, late teens to early 20s. He was wearing a dark-colored tank top over a white t-shirt and gray shorts.
