A man who allegedly assaulted a Somerville man working as an MBTA inspector at Copley station has been ordered to stay off the Green Line.

Daniel Jourdet, of Lynn, allegedly threatened the Somerville man and screamed racist profanities in an April altercation.

Prosecutors said Jourdet, after being informed that the MBTA Transit Police were responding to the incident, exited the station and ran down Boylston Street until he was apprehended by a Boston Police officer. Jourdet allegedly continued to threaten and shout racial epithets at the victim outside the station.

He was ordered last week to stay away from the victim and off the train.

The order specifically prohibits Jourdet from violating the civil rights of the victim and all others in the Commonwealth based upon their actual or perceived race and prohibits him from entering any MBTA Green Line station or traveling on any train of the MBTA Green Line branch. A violation of the injunction is a criminal offense punishable by a fine of up to $5,000 and two and a half years in the House of Correction, or if bodily injury results from such violation, a $10,000 fine and up to 10 years in state prison.

"Our complaint in this case alleges that Mr. Jourdet engaged in a vicious attack on the victim, who was merely attempting to perform his job duties and to ensure the safety of subway passengers," said Attorney General Coakley. "Bias motivated attacks cannot and will not be tolerated in Massachusetts, and we are pleased that the Court has ordered this injunction."
