WEST ORANGE — Two people have been arrested after a police officer was grazed in the head by a gunshot Monday afternoon.

Essex County Prosecutor's Office spokeswoman Katherine Carter said the off-duty West Orange police officer was shot on South Valley Road around 3 p.m.

The officer was intervening in an attempted robbery at a Krauszers convenience store when a single shot was fired, according to West Orange police spokesman Joe Fagan.

Neither Carter nor Fagan disclosed the identity of the officer.

The vehicle used in the shooting was found about 5 miles away in Newark at the Exxon gas station at South Orange Avenue and Bergen Street across from University Hospital.

Two suspects were arrested there, officials said.

Photos show a large police presence surrounding the gas pumps.

West Orange Mayor Robert Parisi told RLS Metro Breaking News the officer is OK.
