A man charged with assaulting a University of Pennsylvania graduate student with a bike lock as she walked near the school's campus has been arraigned.
James Barrett, 55, is being held on $150,000 bail for the attack that took place Thursday night near 41st and Pine Streets, police said. He's charged with Aggravated Assault, Robbery, Theft and related offenses.
Investigators said Barrett dragged the 38-year-old woman down the street after hitting her in the back of the head with the lock. Police stopped the assault as it was happening.
Police are looking at whether Barrett is responsible for four other attacks on female students over the past five days as they walked alone around University City.
The man matches descriptions given by victims in each assault, police said.
