Avenatti is best known as the spotlight-thirsty and Trump-baiting attorney for Stormy Daniels, a perennial cable news guest, and an apparently aspiring Presidential candidate.
He is currently in Los Angeles police custody as of Wednesday afternoon, suspected of beating his estranged wife in the face.
A report on the incident in the Century City area was taken on Tuesday, said Los Angeles police.
News of Avenatti's arrest was first reported by TMZ.
“Avenatti's office did not immediately respond to a request for comment” by BuzzFeed News.
Our law enforcement sources say Avenatti was arrested Wednesday after his estranged wife filed a felony DV report. We're told her face was "swollen and bruised."
Our sources say the alleged incident occurred Tuesday, but there was a confrontation Wednesday between the two at an exclusive apartment building in the Century City area of L.A.
We're told during Wednesday's confrontation the woman ran out of the apartment building and was on the sidewalk on her cellphone with sunglasses covering her eyes, screaming on the phone, "I can't believe you did this to me."
We're told security brought her inside the building and Michael showed up 5 minutes later, ran into the building, chasing after her. He screamed repeatedly, "She hit me first." We're told he angrily added, "This is bulls***, this is f***ing bulls***."
A law enforcement source says on Tuesday, Avenatti "kicked her out of the apartment" and that's presumably when the alleged domestic violence occurred. We're told she went back to the apartment on Wednesday to retrieve her belongings and called police to stand by in case things got heated.
They've been married since 2011. He filed for divorce in 2017.
We're told Avenatti is currently in custody.
