Los Angeles police have opened a criminal investigation into Charlie Sheen, ET can confirm.
LAPD received a radio call on March 31 around 3:00 p.m. of a criminal investigation in which the 50-year-old actor is listed as a suspect, an LAPD spokesperson told ET on Wednesday. The Threat Management Unit -- which supervises investigations involving aggravated threats of violence and stalking, workplace violence, and all threats directed to Los Angeles city officials -- are now the lead detectives in the investigation.
As the case is ongoing, police have declined to release any specific names.
John C. Taylor, a lawyer representing Sheen’s ex-fiancée Scottine Ross, confirms to ET that the investigation involves Ross. The 26-year-old, who's better known as Brett Rossi, went to police regarding threats Sheen allegedly made and has also filed an emergency protective order against the actor, according to her lawyer.
“She takes this very seriously,” Taylor tells ET. “She intends to do everything she can to protect herself.”
The LAPD says they have not reached out to Sheen yet. ET has reached out to Sheen's rep, who had no comment.
ET sat down with Rossi
last December, after she filed a lawsuit
against the Two and a Half Men
star. Rossi, who was engaged to Sheen for nine months in 2014, is suing the actor for assault, battery, emotional distress, false imprisonment, and negligence, claiming he was “violent and abusive and uncontrollable” while abusing drugs and alcohol during the time the two were together.
“I’m tired of being scared,” Rossi told ET. “I’m scared of Charlie. I’m scared of the backlash.”
"I still think I miss what we could have had,” she added about their former relationship. “But at the end of the day, he's an addict. He only loves himself, he never loved me."
Sheen’s lawyer, Marty Singer, has denied all of Rossi’s claims on his client’s behalf.
"Charlie Sheen intends to vigorously defend the lawsuit filed by Brett Rossi aka Scottine Ross. Numerous witnesses will dispute each and every claim made by Ms. Rossi," Singer said in a statement to ET. "We are confident that Mr. Sheen will prevail in this action and also will recover significant damages against her in connection with a pending arbitration that was commenced months ago."
Sheen made headlines in November, when he confirmed that he was HIV-positive
on the Today show.
"I have a responsibility now to better myself and to help a lot of other people," he told Today show co-host Matt Lauer. "And hopefully with what we're doing today, others may come forward and say, 'Thanks Charlie. Thanks for kicking the door open.'"
