ANAHEIM, Calif.-- A bomb squad on Sunday afternoon was investigating a pipe bomb explosion in Anaheim, authorities said.
An explosive device was detonated near the corner of E. Wilhelmina Street and Anaheim Boulevard, the Anaheim Police Department said, CBS Los Angeles reported.
Anaheim police Sgt. Daron Wyatt says police found a pipe bomb blast had caused minor damage to the concrete wall of a closed business and a utility pole.
No injuries were reported.
Wyatt says an end-cap of the device flew 45 feet and put a hole in a wooden fence.
Nearby homes were voluntarily evacuated for about an hour until a bomb squad determined there were no other devices.
Two other pipe bombs exploded in Anaheim in November and December. Wyatt says it's unclear whether this one is related but notes there was an arrest in the previous explosions.
