'Jersey Shore' Star Ronnie Ortiz-Magro Tased & Arrested in Alleged Domestic Abuse Incident

Ronnie Ortiz-Magro has been arrested.

The 33-year-old Jersey Shore star is in police custody after allegedly hitting his girlfriend Jen Harley and chasing her with a knife, forcing cops to tase him, TMZ reported on Friday morning (October 4).

The two reportedly got into a heated argument around 2:30 in the morning at an Airbnb in Los Angeles. It then apparently became physical, with Ronnie allegedly slapping and punching Jen, who ran out of the house.

He allegedly chased after her with a knife, also with their 18-month-old daughter Ariana while yelling at her to get back into the house.

Police reportedly broke down the door to the house, and Ronnie would not leave peacefully, so he was tased. Paramedics checked out both Jen and the baby, and Jen apparently has visible marks on her face.
