Police are asking for the public’s help in identifying a man wanted for assaulting two MTA train conductors in Brooklyn.

Officers say a man punched a train conductor on his arm as he was conducting a safety check on the 5 train.

About 7 minutes later, as the 2 train was stopped at the station, police say the man then approached the conductor's car, reached inside and punched the MTA employee in the face before spitting on him.

Authorities say these incidents happened Thursday afternoon inside the Prospect Avenue station.
