Search warrant at Grover Beach home related to detonation of ‘multiple destructive devices’

A search warrant that police served at a home in the 200 block of South 10th Street early Tuesday morning was related to an “ongoing investigation into the illegal detonation of multiple destructive devices,” according to a news release from the Grover Beach police Department.

Authorities arrived at the home at about 5:30 a.m. Tuesday, according to the police department.

In addition to Grover Beach police, the San Luis Obispo County Regional SWAT Team, the San Luis Obispo County Sheriff’s Office SWAT Team and the San Luis Obispo County Bomb Task Force helped serve the warrant. Police asked the agencies to assist “due to public safety concerns and an abundance of caution,” police said.

Five people were detained at the home and one of them was cited for being under the influence of narcotics, police said. All were later released.

The first incident happened on Oct. 15, 2018, when police and other agencies responded to Grover Beach Elementary School for a “suspected destructive device,” police said. That device was a container of bubbling liquid that was deemed to not be explosive.

In February, destructive devices were set off in the 900 block of Ramona Avenue and the 100 block of South 9th Street in Grover Beach, police said. No one was injured by any of the detonations.

The investigation into the incidents led police to obtain a search warrant for the home, which is in close proximity to where each of the devices were found, police said.

The investigation is ongoing. Police ask anyone with information to contact Det. Nelida Aceves at 805-473-4511 or People can also contact Officer Matthew Goodman at
