Four charged with slicing, tasing, beating man on the Red Line in robbery attempt; one also charged for crowbar beatings, robberies on the Green Line

Two men and two women face charges that they broke a Red Line rider's nose, sliced his jacket and tased him during a robbery attempt on a Red Line train in the tunnel between Broadway and South Station shortly before 7:30 p.m. on Jan. 25, the Suffolk County District Attorney's office reports.

One of the four, Bryan Fitzpatrick, 19, of Walpole, was also charged with being part of a separate group of four robbers with a crowbar who beat, robbed and threatened Green Line riders on Jan. 12.

According to the DA's office, Transit Police officers responded to South Station on Jan. 25 and that:

a man told them that two men and two women had approached him and attempted to take his bag on the train between Broadway and South Station. When the victim did not release the bag, the four punched and kicked him, and attacked him with a knife and a taser. The victim suffered facial injuries and his jacket was slashed in the attack. The four assailants were captured on MBTA video fleeing South Station.

Using the surveillance video and descriptions provided by the victim and witnesses, police identified and arrested the four suspects in and around Harvard Square on Thursday and Friday.

Ny-Jaya Sampson, 19, of Boston, Seth Burns, 20, of Manchester, NH and Sidney Amaral, 23, of Cambridge were arraigned in Boston Municipal Court yesterday on four counts of assault and battery with a dangerous weapon and single counts of assault and battery and assault to rob.

Judge John Garland ordered Sampson held in lieu of $1,000 bail, and to stay away from the MBTA and from her co-defendants. Burns had bail set at $2,000 with similar stay-away orders. Amaral's bail was set at $2,000 but the judge ordered her held for 90 days after revoking her bail on other open cases, the DA's office reports.

Fitzpatrick will be arraigned on the Red Line charges at a later date, the DA's office reports. Fitzpatrick was instead arraigned Friday in Roxbury Municipal court for his alleged role in the Jan. 12 Green Line attacks. In that case, Judge Kenneth Fiandaca set his bail at $10,000 - but also ordered him held for 90 days without bail after holding a dangerousness hearing and concluding he was a potential menace to society.

Innocent, etc.
