Police issued an update this morning about last night's arrest, including the charges that will be filed against the four teens.
Newton Police arrested four Newton teens tonight in connection with a handgun that was reportedly spotted on an MBTA train and later discarded near the T station.
According to a press release issued this evening, police responded to Union Street Wednesday night around 7 p.m. for reports of a person in possession of a handgun.
Police responded to the scene after a witness on the train called police to report someone had dropped a handgun on the floor of the Green Line outbound train. The witness told police the man who dropped the handgun got off at the Newton Centre stop with another male.
When police arrived on scene to investigate, they spotted four males flee the area. One of the males, who ran back toward the T stop, reportedly reached into his waistband and discarded an object.
An officer pursued the suspect and found that the suspect had discarded a small automatic loaded handgun, the press release said.
Officers continued to pursue the suspect and eventually arrested him on Chesley Road. He was identified as a 16-year-old male from Newton.
After an "extensive search" of Newton Centre, police were able to find and arrest the other three individuals who initially fled. Two of the individuals are 18-years old and the third suspect is 15-years old.
All suspects are Newton residents, reports said, and all are facing numerous firearm and ammunition charges as well as conspiracy.
Police did not have any additional information on the suspects.
"The Newton Police Department is very proud of the excellent work of its officers in apprehending all four individuals," the press release said.
