When he returned to retrieve the firearm around 1:30 p.m., cops ​were waiting and arrested him.

A maid had previously gone in to confiscate the gun, wrapped it in a towel, and handed it over to ​police.

The firearm had seven rounds ​in it, according to prosecutors, who said Flock told officers​,​ “I didn’t know it was such a big deal.”

Defense attorney Dara Hebert said her client had just been in town doing “touristy stuff,” like visiting the Statue of Liberty and Times Square.

North Carolina is an open-gun state, Hebert added, saying her client ​did not need a license to purchase the weapon there.

His gal pal and her father, who were in court with him, declined to comment.
