AceShowbiz - Ronnie Ortiz-Magro was put in custody for assaulting his on/off girlfriend Jen Harley during their stay at an Airbnb in Los Angeles. According to a police spokesperson, the officer had to use stun gun to subdue the former star of "Jersey Shore" because he was uncooperative.

Ortiz-Magro had a heated argument with baby mama Harley in the early morning of October 4 in Los Angeles. He then hit her and chased her with a knife when she ran out of the house. Their 18-month-old daughter Ariana Sky was with them when the altercation happened. The reality TV star locked himself in the house with his kid when the cop arrived and refused to come out, so police broke down the door.

"Officers responded to a battery in progress in the 7200 block of Woodrow Wilson Drive at around 2:40 a.m.," the LAPD spokesperson said. "Suspect and victim were involved in some kind of physical altercation. When officers [were] on location, the suspect was uncooperative. Officers had to use a taser so there was minor use of force that occurred."

"There was no further incident," the officer added. "A child at the location was not harmed."

The 33-year-old TV personality and his baby mama had no major injuries. He was shirtless and handcuffed to a stretcher when taken to jail while she reportedly had visible marks on her face. Hours before the incident, the two attended a party together.

Ronnie Ortiz-Magro and Jen Harley had a tumultuous relationship filled with explosive arguments and alleged abuse on both sides. On New Year's Eve, she reportedly hurled an ashtray at Ortiz-Magro during a party at the Las Vegas strip club Hustler.
