A man broke into a Queens grocery store and ran off with 10 jars of tomato sauce, assaulting security on his way out, cops said Saturday.

The thief snuck into the basement of a Food Universe grocery store on 75th Street near 31st Avenue in Jackson Heights at about 11:30 p.m. on July 20, cops said.

When he attempted to leave with the armful of sauce jars, a security guard blocked him.

The man took out a pipe wrench and struck the security guard on the arm, then fled, authorities said.

The guard refused medical attention at the scene.

The investigation is ongoing and no arrests have been made.
