Bomb squad personnel are investigating a pipe bomb that exploded Sunday afternoon in an alley in Anaheim, police said.
No injuries were reported but some homes were briefly evacuated during the investigation.
Officers were called at about 1:50 p.m. to the 600 block of North Anaheim Boulevard near Wilhelmina Street after a report of an explosion, said Anaheim police Sgt. Daron Wyatt.
The bomb, which appeared to be of a metal material, was set on the ground at the base of a light pole against a concrete wall separating commercial buildings to the east and residences to the west, Wyatt said.
It detonated with such a force that “one of the end caps blew a clean hole, almost as if a saw had cut it,” through a wooden fence about 40 feet south of the pole, Wyatt said.
Some minor charring and damage was visible on the concrete wall and pole.
People who were evacuated in some homes in the area around Alberta Street were allowed to return to by about 3 p.m., Wyatt said.
Tammy Farrell, 46, said she was inside a home right by the alley when she heard the explosion.
“I thought something actually fell from the sky, from like an airplane, because it was so loud,” she said.
