A man has been arrested and charged after he allegedly assaulted a woman on Metro’s Green Line, authorities said.

The incident happened about 11:45 a.m. Sunday at the Branch Avenue station. Metro Transit Police said the victim was allegedly assaulted by a man who was later identified as Marcus Mullins, 33, of Waldorf, Md.

In a statement, a Metro spokesman said that “due to his mental state, Mullins was involuntarily committed for a mental health evaluation” and was released. Transit Police then got a warrant for his arrest on a charge of second-degree assault.

He was wanted on that charge, said Metro spokeswoman Ian Jannetta. On Wednesday, Metro officials said in a Twitter message that police had arrested Mullins “without incident this morning at a residence in Capitol Heights.”
