Police say the woman told police that she was walking down Sherman Avenue early Saturday when she was approached by Thompson.
She says Thompson led her to a house where he punched her in the face repeatedly and sexually assaulted her. Police say the woman escaped and flagged down a police officer when her attacker fell asleep.
A Robert Thompson on the Pennsylvania sex registry database shows he was convicted of rape in 1990 and is from Philadelphia.
