A man is facing charges after police said he sexually assaulted a woman while she was sleeping on a Greyhound bus driving through Pittsburgh on Tuesday.
Authorities said Derek Johnson, 55, was arrested at the downtown bus station after the victim reported the incident to the driver, who detained Johnson until officers arrived.
According to police, the victim said Johnson originally sat behind her on the bus, and he made her feel uncomfortable. She said he then came and sat next to her.
The victim told investigators she asked him to leave, and he did. She said he then came back again and sat next to her. This time, the victim said, he put a blanket over both of them and sexually assaulted her while she was asleep.
Police said Johnson, who was on his way from Florida to Seattle, was charged with aggravated indecent assault. He remains in the Allegheny County Jail.
Greyhound officials released the following statement Thursday regarding the incident: "Safety and security of passengers is our top priority. If passengers are concerned while riding Greyhound, we ask that they immediately notify their driver or staff member."
