Metro North employee Will Pepe was recognized by both colleagues and management from a photo distributed by law enforcement.
MTA management moved swiftly, and Pepe was suspended without pay and charges will be filed next week.
"Effective immediately this individual has been suspended from Metro-North without pay and will be disciplined in accordance with his collective bargaining agreement pending an investigation," said Ken Lovett of the MTA. "This alleged conduct is abhorrent and goes against the values of Metro-North, New York and the nation."
Pepe called in sick Wednesday to attend the Capitol protest, which is false use of sick leave.
