“Jersey Shore” star Ronnie Ortiz-Magro has been arrested on charges of kidnapping after a domestic dispute involving his on-off girlfriend, Jen Harley, and their 18-month-old daughter, Ariana.

The incident is the latest in what have been a series of allegedly violent encounters between Ortiz-Magro, 33, and Harley.

Fox 11 Los Angeles reports that neighbors called 911 in the Hollywood Hills just before 3 a.m. on Friday, reporting that Harley was running down the street screaming for help, saying someone took her baby daughter. A witness said a shirtless man attacked Harley. Neighbors said the couple had been renting the property. (Harley and Ortiz-Magro live in Las Vegas.)

On Thursday, Ortiz-Magro and Harley were seen holding hands.

When Los Angeles police officers ordered Ortiz-Magro out of the home, he reportedly refused, and was holding Ariana. Officers broke down the door and used a Taser on the reality show star after he allegedly tried to fight police. Ortiz-Magro was handcuffed and taken to a hospital. Harley reportedly had minor injuries and Ariana was not hurt.

Ortiz-Magro was released from the hospital into police custody. Bail was set at $100,000.

In January, Harley was alleged to have thrown an ashtray at Ortiz-Magro’s head at a New Year’s Eve party in Las Vegas. In May, she was arrested on suspicion of domestic battery after she reportedly called the police to say that someone had a gun. Police discovered that Harley had an outstanding warrant from the January incident. Ultimately, she did not face domestic violence charges.

In 2018, a domestic battery charge was dropped against Harley because of a lack of evidence after she was alleged to have hit Ortiz-Magro in the face and dragged him from her car when he asked to get out of the vehicle.

One storyline on the MTV “Jersey Shore” revival “Jersey Shore Family Vacation” has been that Ortiz-Magro lied to his castmates about being jumped in Secaucus as a cover story to explain scratches on his face from another alleged domestic dispute. Cast members have said they believe that Harley physically abuses Ortiz-Magro, and previously advised him to seek custody of Ariana. Still, Ortiz-Magro and Harley have attempted to patch things up and presented a public face of reconciliation.

The ongoing drama between Ortiz-Magro an Harley has often played out on social media, in addition to TMZ. In October of 2018, Ortiz-Magro posted a photo showing a black eye and bruises.
