Philly police were seeking a man who they said ran up to a woman and smacked her in the face last week, leaving her with a laceration.

Police said Tuesday they had no information about a motive or what led to the crime.

According to the police report, the victim, a 51-year-old female, was walking on the 2700 block of Pennsylvania Avenue — a dark, secluded street that borders the Fairmount neighborhood and is adjacent to subterranean railroad tracks — when the attack occurred on Nov. 4 around 4:05 p.m.
