66-Year-Old Man Struck and Killed By Red Line Train

A 66-year-old man was struck and killed by a Red Line train at the Porter Square station Sunday morning, Massachusetts Bay Transportation Authority transit police announced over the weekend.

The man— who has yet to be identified by authorities — was in the northbound tunnel when he was struck by the train at approximately 7 a.m., according to police.

Multiple transit police officers responded to calls alongside officials from the Cambridge Fire Department and EMS. The man died of injuries sustained from the impact, per police.

Officials said no foul play is suspected, though the Middlesex District Attorney’s Office has opened an investigation into the incident.

Red Line service was temporarily shut down and shuttle buses replaced trains from Harvard Square to Alewife stations. But trains were back up and running by 9:45 a.m., according to MBTA officials.
