A Maryland woman was stabbed with a syringe filled with semen, cops said Friday.

Thomas Byron Stemen, 51, was arrested by Anne Arundel Police on Tuesday after a woman reported that she was assaulted while grocery shopping on Feb. 18, cops said in a press release.

Surveillance video shows Stemen pretending to bump into the woman as she was returning a shopping cart, jabbing her with an object he pulled from his pocket.

The victim — identified by WBAL-TV as Katie Peters — initially thought she was burned by a cigarette butt, the station reported.

“It felt like a bee sting didn’t it?” Stemen allegedly told Peters after the attack, the outlet reported.

Cops said they received an anonymous tip on Tuesday which named the 51-year-old as the attacker.

Investigators then found the syringe in the driver’s side door of his car, WBAL-TV reported.

Stemen was arrested and charged with first- and second-degree assault and reckless endangerment. A judge ordered he be held without bail.

Peters told the station on Wednesday that she felt safer with Stemen behind bars.

Cops said that additional testing and investigations are underway — believing that there may be additional victims.

It was unclear Friday whether Peters and Stemen knew each other.

“This investigation is extremely active additional charges may be applicable,” cops posted on Twitter.

Jail records show that Stemen is housed in the Jennifer Road Detention Center.
