A Massachusetts woman is suing the town of Hopkinton, alleging officials negligently approved a criminal immigrant with a history of workplace sexual violence to operate a business where he later assaulted the plaintiff when she was 16 years old.
The lawsuit, transferred to federal court Jan. 5, names Greek national Petros “Peter” Sismanis, who is in Immigration and Customs Enforcement (ICE) custody. According to court documents, Sismanis was convicted in June 2025 for the 2023 sexual assault of the plaintiff while she worked at Hillers Pizza.
The complaint also notes that Sismanis was previously accused in 1998 of rape, indecent assault and battery involving female minors, which resulted in his registration as a sex offender. NBC Boston reported he assaulted two employees while operating a donut shop in Hopkinton.

The plaintiff, now 19, claimed Hopkinton officials, the police chief and Hillers Pizza all played a role in fostering a sexually hostile work environment. She alleges that town officials knew, or should have known, about Sismanis’s criminal history when he renewed Hillers Pizza’s license in 2016, a process that requires review by multiple town departments, including the police.

Editors note: Overall we don’t know if owning a business or Not being Allowed, to own or operate a business was any violation of parole, offenders registration obligation etc… If not, it certainly seems not granting or even renewing a business license by the City would open them up to a lawsuit? Not saying it isn’t common sense to not have a Sex Offender working in a business that frequently has children as customers…. but it seems common sense and the law rarely overlap. Maybe that’s the whole point of this lawsuit?
Stay Tuned as they say.
