Sheriff's deputies took two suspects into custody after an attempted armed robbery of a jewelry store in unincorporated Menlo Park Wednesday afternoon.

Deputies received a call at 12:27 p.m. alerting them of an armed robbery at the Plaza Jewelers at 3303 Middlefield Road in unincorporated Menlo Park, according to sheriff's office spokeswoman Rebecca Rosenblatt.

Witnesses say four dark-skinned males in a white sedan used a handgun in an attempt to rob the store, Rosenblatt said.

Deputies arrived within 30 seconds of the call and followed the suspect vehicle until it crashed into an uninvolved civilian's vehicle at Marsh and Bay roads at 12:32 p.m.

The suspects fled on foot forcing officers to lock down the area and conduct a yard-to-yard search, at one point using the California Highway Patrol's plane.

Two suspects were apprehended and the handgun allegedly used in the attempted robbery was recovered. Two suspects remain at large.

No schools were locked down and the area around Marsh and Bay roads was cleared just after 4 p.m.

The investigation is ongoing.
