Amtrak police arrested a passenger outside of Penn Station early Saturday after the man brandished a handgun, sources told The Post.

Eddie James Tensely, 40, allegedly got into an argument with a woman near the corner of 31st Street and Eighth Avenue after arriving on a train from Chicago around 2 a.m., the sources said.

When Amtrak police approached Tensley, he allegedly drew a .38 caliber gun and handed it to Amtrak officers in an apparent attempt to have himself arrested.

“Lock me up; I want to go to jail,” Tensley said, according to sources.

Amtrak police obliged and placed him under arrest.

Amtrak did not immediately respond to a request for comment.
