"Many a New Yorker has fantasized about kicking back with a cold beer in a prime piece of Manhattan real estate -- especially one this close to good transportation," MTA Inspector General Carolyn Pokorny said in a statement. "But few would have the chutzpah to commandeer a secret room beneath Grand Central Terminal and make it their very own man-cave, sustained with MTA resources, and maintained at our riders' expense."
The "man cave," located behind a locked door in a locksmith shop storage room below Track 114 at Grand Central Terminal, was not known to station management, investigators said.
Three MTA employees -- a wireman, a carpenter and an electrician -- have been suspended without pay in connection with the investigation, officials said.
MTA officials said a project is now underway to map off the rooms at Grand Central to ensure they are all being used for proper purposes.
