After the recent murder of a 15-year-old boy outside the Dudley Square bus station, MBTA officials are considering adding a police post at the station, which has seen other violent acts in recent months.

On the evening of Feb. 14, East Boston High School freshman Shawn Adams was stabbed in the chest and killed in an altercation between two groups of teenagers who were gathered on Dudley station’s Silver Line platform.

Adams’s slaying is the second murder at the station in the past four months.

Massachusetts Bay Transportation Authority spokeswoman Lydia Rivera said MBTA authorities are considering installing a new MBTA police sub-station at Dudley, a plan they are “taking very seriously” because of the incident.

“It’s in an infantile stage,” Rivera said. She added that there is no timeline yet, but that but the sub-station should be built “sooner than later.”

A police officer is assigned to the Dudley bus station during normal operating hours, from 7 a.m. until midnight. However, according to previously released MBTA police reports, the officer on duty was at the Ruggles station dealing with another incident at the time of last Saturday’s slaying.

“Sometimes unfortunate incidents do occur,” Rivera said. The MBTA advises youths not to congregate inside stations unless they are about to ride on buses or trains, she added.

“They could have prevented it,” a Roxbury woman who identified herself as Q. Brown said of the slaying. She said a friend of her family was recently murdered near the station. “And now this kid got killed,” she added.

Tina Brooks, another area resident, said the opening of an MBTA police station would not be useful.

“Patrolling the area would be more effective,” Brooks said, pointing out that “there’s a police station down the street.” She was referring to the District B-2 station, located nearby at 135 Dudley St.

The MBTA police and Boston police work closely and cooperatively, Rivera said. She said Boston police tended to the wounded teenager.
