A Massachusetts man assaulted a conductor Wednesday night after the conductor asked him to put on a mask, authorities say. 

The conductor told Daniel Libby, 40, that face masks were required on the train. Libby then allegedly shoved the conductor and used his shoulder to force his way off the train. 

The conductor called Massachusetts Bay Transport Authority (MBTA) Transit Police at 5:20 p.m. to assist in the situation, NECN reported.

Police say that Libby refused to cooperate with officers or provide his name when officers told him the victim wished to press charges. 

Instead, Libby responded with "several expletives," CBS Boston reported.

"Libby refused to cooperate with the officers and would not comply with any requests," MBTA Transit Police said.

Face coverings are required on all public transit and in stations within the MBTA system – even if the individual is fully vaccinated.
