The reality star reportedly got into another altercation with his on-off girlfriend, Jen Harley.
Ronnie Ortiz-Magro has been arrested.
ET has learned that the 33-year-old Jersey Shore star was arrested early Friday morning after an alleged incident with on-off girlfriend Jen Harley.
A spokesperson for the Los Angeles Police Department tells ET that they received a call at 2:40 a.m. on Friday morning at a Los Angeles house for an "reported battery in progress." When police arrived on the scene, they had to use a taser on the suspect, who was involved in an alleged altercation with a female victim.
The police spokesperson also tells ET that there was a child at the location of the alleged incident, but they were unharmed. As for the alleged female victim, she appeared to have suffered minor injuries but was not transported to a hospital, says police. The suspect, however, did go to the hospital for medical attention before being booked at a nearby jail.
A spokesperson for the LAPD tells ET that Ronnie was booked for kidnapping at LAPD's Van Nuys station, and was released on $100,000 bail.
According to TMZ, Ronnie allegedly attacked Jen, who left the couple's AirBNB screaming and running from the house. Police received multiple 911 calls reporting Jen's alleged distress.
The Jersey Shore star then allegedly chased after Jen with a knife in one hand and their 18-month-old daughter, Ariana, in the other. According to multiple reports, Ronnie then dropped the knife and locked himself and his daughter in the house.
When police arrived to the scene, Ronnie refused to exit the home, so authorities kicked down the door and eventually had to taser him to get him into police custody.
In a statement obtained by ET, the reality star's attorney, Scott E. Leemon, says, "The reporting of the alleged incident relating to Ronnie Magro yesterday is based upon pure speculation and innuendo. We are currently conducting our own investigation and will have no further comment until that has been concluded."
Meanwhile, in lead-up to the alleged incident, ET learned that Ronnie attended a private party with friends and family to celebrate the launch of his CBD company, Verge, at Poppy in West Hollywood. Ronnie arrived with Jen, and according to an attendee, they were both mingling.
"[Ronnie] was in good spirits and having fun. It was his party and he was laughing and doing a bunch of Instagramming live stories," the attendee tells ET.
Near the end of the evening, however, the attendee says Jen appeared agitated and worked up, and the couple left at 11 p.m.
In early September the couple split after Jen accused Ronnie of cheating on her, but TMZ had footage of the pair back together just hours before this alleged altercation.
ET got to know Ronnie as a single dad this past summer when the reality star invited Sophie Schillaci into his home.
"Fatherhood has changed me a lot. It's given me purpose, it's given me meaning," Ronnie said at the time.
