Two more dry ice bombs exploded in the neighborhood behind Granary Square in Valencia Sunday night, according to sheriff’s officials, bringing the weekend total for “bomb” discoveries to four.

Sgt. Richard Nagler said that deputies found three of the primitive devices in different Arbor Park driveways shortly after 9 p.m. Two of them blew up and the third was disarmed by Arson and Explosives personnel.

The bombs caused no damage and Nagler said that the suspects are most likely juveniles playing practical jokes. No arrests were made.

On Saturday afternoon, arson investigators diffused a dry ice bomb in a water bottle in front of a gate on Valley Street in Newhall.
