The Sunday morning arrest happened after LaBella and the 26-year-old actress had a disagreement at her hotel in New York.
“Lindsay was assaulted early this morning in a New York hotel. While she did sustain some injuries, she was not hospitalized,” Lohan’s rep Steve Honig tells Celebuzz.
“The assailant was arrested and is currently in police custody. Lindsay has spoken with police and is fully cooperating with the investigation,” he added.
According to NBC New York, Lohan had told authorities that she had met LaBella, 25, at 1 Oak, a nightclub in the Chelsea neighborhood of Manhattan.
But what led to the arrest of LaBella, and what were the two arguing about?
After leaving the nightclub for her hotel room early Sunday morning, Lohan reportedly noticed that LaBella had snapped photos of her on his phone. Lohan told authorities that LaBella then engaged in a series of attacks on her, which included choking and throwing her to the ground and then climbing on top of her.
NBC New York reports that Lohan’s friends, who were with her at the time, successfully pulled the man away, allowing the Mean Girls star to reach for the fire alarm for help.
Authorities later charged LaBella with assault and harassment.
