San Luis Obispo County Sheriff’s Office narcotics investigators served a search warrant at a home in the 1700 block of Farrier Court in San Luis Obispo on Wednesday and found what they called a “suspected butane honey oil conversion lab.”

Michael Allan Siegfried, 28, of San Luis Obispo was arrested on suspicion of manufacturing a controlled substance, sale of a controlled substance and assault on a police officer.

In a news release, the Sheriff's Office said the lab uses butane to convert low-concentrated marijuana into hash oil, adding that the process is dangerous and “can result in explosions like those which have occurred in San Luis Obispo, Morro Bay, Los Osos, and Templeton in the past several years.”

The lab was across the street from a home daycare center, the release said.

Agents confiscated 30 pounds of packaged marijuana, 80 pounds of marijuana suspected of being used in the oil-extraction process, more than $15,000 in cash and several assault-style weapons, the release said.

The Sheriff's Office said Siegfried was part of an operation that ships marijuana out of the state. More arrests are expected.
