41-year-old Joseph Woods was arrested last month for the rape of a 21-year-old woman.
Police say Woods was caught on SEPTA surveillance before he dragged the woman into an alley then raped and robbed her.
Today, police announced DNA linked Woods to another subway attack at Broad Street and Lehigh Avenue back in March.
In that incident, the victim was just 15 years old.
Woods remains behind bars tonight.
