A repeat groper assaulted a woman on an uptown 6 train and ran off into a tunnel, evading police for days, according to a police report.

The victim told police she got on the crowded train with a friend at Grand Central-42nd Street at 5 p.m. Feb. 2 and Laimant McDonald, 28, followed her on, according to a report.

Using the packed car as cover, he repeatedly rubbed his crotch against her and continued to do so even as the woman tried to edge away from him, police said.

Not wanting to make a scene, the woman made eye contact with her friend to try to get someone’s attention and the pair notified police at the Lexington Avenue/51st Street station, according to a report.

When officers moved in to arrest McDonald, he left the train, jumped onto the tracks and ran into the tunnel, police said.

Based on the victim’s description, officers identified McDonald who was known to them as a serial train predator, according to a police report.
