The probe was launched after three women came forward and reported they were sexually assaulted by Masterson in the early 2000s, Officer Drake Madison, a Los Angeles police spokesman, said on 3 November. He declined to provide any further details, citing the ongoing investigation.
The 40-year-old actor is best known for his role as Steven Hyde on That 70s Show, which aired from 1998 until 2006.
A representative for Masterson, who has not been charged with a crime, denied the allegations in a statement on 3 November, saying one of the accusers was his longtime girlfriend who continued to date him after the alleged incident.
“The alleged incident occurred in the middle of their six-year relationship, after which she continued to be his longtime girlfriend,” the statement said.
Masterson’s statement also said another one of the accusers had brought the same allegations to the LAPD about 14 years ago but police “determined the claim had no merit.”
