Police are investigating an early morning robbery and stabbing in the city's Fairmount Park section, just blocks from the Philadelphia Museum of Art.
A 32-year-old man who lives in the area was walking in the 2700 block of Pennsylvania Avenue at about 4:35 a.m. when a man came up behind him and pressed an object into his back, saying it was a gun, police said.
The unidentified suspect forced the victim into a wooded area behind a nearby playground. When the victim turned and faced his attacker, he realized the assailant was actually carrying a knife, authorities said.
