LAS VEGAS (AP) - Officials say a Las Vegas police officer who stumbled upon a robbery at a 7-Eleven helped foil the crime.

Authorities say an officer who pulled up to the convenience store on Lake Mead and Jones boulevards about 2 a.m. Tuesday was warned about the crime in progress by two people.

Officials say the officer walked up to the store and saw a man pointing a gun at the clerk.

Metro deputy police chief Kathy O'Connor tells Fox 5 the suspect turned the gun toward the officer, and the officer fired at him.

The suspect was taken to University Medical Center in critical condition.

Authorities say a second suspect was found hiding in the store.
