Influencer Brianna Olsen‘s ex Santos Salazar is in police custody for alleged attempted murder.

The 21-year-old was booked into a Los Angeles jail on a felony charge around 4:45 a.m. Thursday, Aug. 13, and is being held on $1 million bail, according to records obtained by USA TODAY.

The arrest came just after midnight, when the Los Angeles Police Department responded to a reported domestic violence incident, a spokesperson for the LAPD tells USA TODAY. The investigation revealed information that “resulted in the arrest of an adult male suspect” for attempted murder.

The call was to an address belonging to Salazar and Olsen, USA TODAY can confirm. As of Friday, Aug. 14, Salazar is behind bars, and the investigation remains ongoing.

Salazar and Olsen are known for their online presence, particularly on Snapchat and TikTok. They previously dated and share a son, Sunday Ray, whom they welcomed earlier this year and have posted on their social media in recent months.

Salazar appears to have a daughter from a past relationship as well. He celebrated her third birthday in his most recent TikTok, shared Saturday, Aug. 8, just days before his arrest.

Along with the clip, showing him and the child when she was a baby, he wrote, “I pray every day you’re safe and happy princess.., happy birthday mi niña hermosa.” He also added a hashtag about parental alienation.

News of Salazar’s arrest began circulating online in the early hours of Aug. 13, when Olsen reportedly posted a clip of him being handcuffed on Snapchat, according to a video obtained by TMZ.

“I’m so sorry guys….,” the influencer wrote across the screen.

She later allegedly discussed the situation on a livestream, during which she assured she and their son were safe and appeared to call Salazar in jail, according to alleged reposts of the stream.
