Police have arrested one half of the now-infamous couple that paused for a blow job in the middle of a Boston subway platform last Friday.

The Boston Globe reports that officers from Special Crimes Unit arrested Philip Urban, 50, last night in Malden, Mass., and charged him with open and gross lewdness.

The jorts-wearing Urban allegedly received oral sex from a still unidentified woman in the middle of the T platform at the State Street station last Friday at about 2:30 pm. Police identified him after a photo of the sex act—taken by a concerned straphanger—went viral.

“We received some tips, but we put a lot of time into reviewing images from our public safety cameras, and we were able to track him to Malden,” Transit Police Lieutenant Richard Sullivan told the Globe. “Conduct like that is not going to be tolerated.”

If convicted, Urban could be sentenced to three years in state prison and be ordered to pay a $300 fine. He would also be required to register on the state’s sex offender list.
