MEDFORD — A man allegedly attacked a Transit Police officer at Harvard Square Station Monday after he was thrown out for trying to evade a $2.75 fare, a confrontation in which the officer was stuck by a hypodermic needle and suffered cuts around his mouth.

Travis Artist, 36, of Somerville, appeared in Cambridge District Court Tuesday, where he complained loudly to a judge who revoked his bail on a previous case because of his latest arrest. He’ll be in custody for at least 90 days.

“Ninety days for a misdemeanor?’’ Artist yelled as he was escorted out of the prisoner’s area. “That’s [expletive] crazy!’’ Screams could be heard after he was taken out of the courtroom. Artist has pleaded not guilty.

The altercation with police began around 3:30 p.m. Monday, when an officer allegedly saw Artist enter the Red Line station without paying, Transit Police said in a statement.

The officer issued him a citation, ordered him to leave, and issued a nontrespass order, police said.

Artist allegedly returned 10 minutes later.

“The officer approached and explained that due to his tumultuous behavior moments earlier he would have to exit the station,’’ police said. “As the officer was escorting Artist out of the station Artist became verbally aggressive.’’

According to a police report filed in court, a struggle broke out after the officer ordered Artist to put his hands behind his back.

“He disobeyed my commands and fled from me,’’ the officer wrote in the report. “Artist then violently stuck [sic] me in the face in an attempt to escape arrest.’’

According to the report, the officer was also stuck by an uncapped needle that was in Artist’s pocket.

The struggle lasted more than two minutes, police said. A private security guard from the Harvard Coop jumped in to help the officer. Cambridge and Harvard University police officers were also involved in the arrest.

The Transit Police officer was hospitalized for evaluation.

Artist faces charges of assault and battery on a police officer, resisting arrest, and trespassing. As a prosecutor read the complaint in court, Artist looked down at the floor and shook his head.

His lawyer, Raymond L. Parino, argued that his client’s account differs from what was outlined in the police report.

Parino said that Artist alleges that a police officer told him he could come back into the station if he paid the fare. According to Parino, his client said he paid the fare, and therefore was in the station legally.

Parino acknowledged that his client has a criminal record. Artist faced multiple cases in Boston Municipal Court between 2014 and 2015, according to court documents.

According to court documents, Artist was already facing pending charges of shoplifting and intimidating a witness in Somerville.
