A manhunt is underway for suspects involved in the shooting of a Woburn police officer at Musto Jewelers at the Four Corners intersection, according to police.

Patrolman Robert DeNapoli was taken to Lahey Clinic where his condition is currently under evaluation, according to Steve Danehy, director of media relations for the hospital. 

The Four Corners intersection remains closed and a command center has been set up there by the Middlesex Sheriff’s office. Police officers are also searching door-to-door in the neighborhood.

SWAT teams, state police and police from surrounding communities, including Wakefield, Lexington, Billerica, Burlington, Waltham, Lincoln and Wilmington are at the scene.

Initial reports say there was a gunfight between police and three or more suspects shortly after 11 a.m on Tuesday. The jewelry store is located on the second floor of a strip mall at 186 Cambridge Rd.

One of the suspects was reportedly shot and apprehended near 180 Lexington St. Another suspect may have been apprehended near the intersection of Cambridge Road and South Bedford Street.

Police are advising people who live in the area to lock their doors. Two schools in the area  -- the Joyce School (grades 6-8) and the Reeves School (grades K-5) are in lock down. Students are not in the buildings as school doesn’t start until later in the week, but teachers and support staff are there.

A K-9 team reportedly found a mask near the scene.

There are reports that one of the suspects was taken to Lahey Clinic by ambulance for a gunshot wound to the abdomen. 

Rick Capobianco, an eyewitness at the scene, said he heard three gunshots, then a pause, and then another three gunshots: one which may have ricocheted off a nearby building.
