A man has been arrested on the suspicion that he stabbed a woman with a syringe filled with semen.

On February 18, a woman reported a man assaulted her with a needle at a Maryland grocery store, in the US, in an attack that was captured on surveillance video.

Investigations led to the arrest of a man named Thomas Bryon Stemen, aged in his 50s, who was allegedly seen on security footage assaulting the woman, then pretending he had nothing to do with it.

Ten days after the incident the Anne Arundel County Police Department learned the substance in syringes found in Stemen’s possession was actually semen.

Video of the attack showed a man following the woman as she entered the store to get a trolley before jolting the item into the side of her body, causing her to reel back in pain and walk backwards out the door.

The man appeared surprised at the woman’s reaction and was shown looking around in an act seemingly trying to fool her into believing he was not responsible.

The woman wasn't identified but police said she received medical treatment.

She told news outlets she was put on preventative medications for 30 days.

Stemen was charged with first and second-degree assault, and reckless endangerment.

It is unclear whether he had an attorney who could comment on his behalf.

Police said there could be more victims who have yet to come forward.

“Additional testing and investigations are under way,” a post to Facebook by the police department read.

“Detectives believe there may be additional victims who have yet to report similar incidents.

“This investigation is extremely active additional charges may be applicable.”
