Police are investigating after two diner workers were attacked over an unpaid bill in Queens earlier this month.

The NYPD says the two men seen in security video didn't pay for their breakfast at the Good Fellas Diner in Maspeth on the morning of October 1.

When a 70-year-old male employee tried to stop them from leaving, he was punched in the face.

A 67-year-old female employee then tried to write down the license number of the men's car.

Police say one of the men snatched her notepad and threw her to the ground.

The woman broke her arm and dislocated her shoulder.

Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-TIPS, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
