MANTECA — Police are searching for a man known to authorities who allegedly entered a Manteca bank on Monday and left behind a suitcase, prompting a bomb squad to respond.

At 4:19 p.m. at the Chase Bank at 115 W. Center St., the man entered with a suitcase and was heard to have been making “unusual” statements, Sgt. Mike Aguilar of the Manteca Police Department said Tuesday.  

Aguilar would not expand on exactly what the man told bank employees, but it was enough for staff to believe the suitcase contained explosive material.

After leaving the suitcase inside, the man then left. Police responded to the scene and notified the San Joaquin County bomb squad.

Using a bomb-diffusing robot, the suitcase was removed from inside the bank and opened, authorities said, revealing there were no explosives or related contraband.

The area around the bank was closed off for several hours and reopened about 7 p.m. Police said there were no injuries.

Aguilar described the subject as black and in his 30s, with a beard, last seen wearing a black jacket, purple shirt and blue jeans. He is well known to Manteca authorities and as of midday Tuesday has not been located.
