Four people were taken into Santa Monica police custody early Friday, September 8th, after officers said they located two homemade explosive devices on Santa Monica Beach.

Police were called to the 1400 block of the beach at 4:38 a.m. regarding a report of suspicious activity.

When officers arrived, they heard several “loud popping noises,” Santa Monica police Lt. Frank Fabrega said.

The officers located and detained four individuals on the beach and during the investigation, found two pipe bombs, police allege.

No injuries were reported.

Police cordoned off the area and notified the Los Angeles County Sheriff’s Department Bomb Squad.

When bomb squad officers arrived they examined the devices and detonated the two pipe bombs on the beach, police said.

Additional explosive devices were recovered at the scene and a large quantity of illegal fireworks was also recovered, police said.

The value of the fireworks is not known, but it is estimated that approximately 3,000 to 4,000 firecrackers, several bottle rockets and several Roman candles were recovered, Fabrega said.

The area of the beach was reopened at 11 a.m.

The four suspects were taken to the Santa Monica Jail and were interviewed by detectives.

The investigation is ongoing.
