The video, recorded late last month and shared widely in recent days, shows parkour instructor Dylan Polin, 23, of Norwood making the jump and landing on the opposite platform.

MBTA Transit Police say they’ll seek a criminal complaint against a Norwood man who was recorded on an Instagram video that showed his leaping flip over the Red Line tracks at the MBTA’s Park Street station.

Lieutenant Detective Richard Sullivan said in an e-mail Tuesday that the “behavior was extremely dangerous and we will not tolerate such conduct.” He said the agency would pursue a criminal complaint, seeking to charge him with trespassing.


He said the charge could result in 30 days in jail or a fine of $100.

Polin could not be immediately reached. He has said he is well trained in the acrobatic street sport of parkour, and would not have attempted the jump if he was not confident he could make it.
