BOSTON (CBS) – Several people helped save a passenger from a frightening accident on the T Thursday afternoon.

The man walked off a Green Line trolley at the Haymarket station just after 12 p.m. , stumbled and suddenly fell beneath the train.

MBTA spokesman Joe Pesaturo said the man was “intoxicated.”

“Preventing a tragedy, customers on the platform alerted the trolley operator of the situation before the train started to move,” Peasturo said in an email to WBZ-TV.

The entire incident was recorded on a surveillance video camera.

The man was not hurt, Pesaturo said.

His name was not released.
