CONCORD -- A 21-year-old Concord man was arrested Wednesday after a search of a residence uncovered some suspected explosive devices, police said.

The arrest came after police called in members of the Walnut Creek Bomb Squad around 2:15 p.m. to assist them with the search of the home in the 1800 block of Johnson Drive, Concord police Sgt. Jeff Crump said. Citing the ongoing investigation, police did not identify the man, who was booked on suspicion of possessing destructive devices, Lt. Robin Heinemann said.

Three neighboring homes were evacuated during the search for precautionary reasons, Crump said.

A member of the bomb squad emerged from the home and gave other officers a thumbs-up sign around 4:30 p.m. Wednesday. Police also removed several boxes from the residence but did not say what was in them.

Nobody was injured during the search, and none of the devices detonated, police said.

The case remains under investigation by the Bureau of Alcohol, Tobacco and Firearms, Crump said.
