Three more youths have been arrested in connection with an attack on the Shawmut MBTA station

Three boys were arrested Friday in connection with an attack on two men at the Shawmut MBTA station in Dorchester on Monday, transit police said.

The minors, who were not identified by name or age, were arrested at about 1:30 p.m. in Harambi Park in Dorchester, transit police said in a statement Saturday.

The arrests come after a 15-year-old boy was detained on Wednesday in connection with the attack on a 69-year-old man and a 47-year-old man on blue bicycle racks in front of the station around 11:50 a.m. Monday, police said.

The men said they were approached by several boys who showed a knife and demanded money, the statement said. When the men said they had no money, the boys allegedly started beating and beating them before fleeing the area, police said.

The victims were treated at the scene by the Boston EMS. Police say the investigation into the attack is ongoing.
