BERKELEY -- Three people were arrested and part of Oregon Street was shut down Friday morning after Alameda County sheriff's deputies serving a drug-related search warrant uncovered some potentially hazardous chemicals inside a house, authorities said.

The sheriff's department's special investigation unit served a search warrant about 8 a.m. at a home in the 1600 block of Oregon Street, where a resident was suspected of manufacturing and selling LSD and Ecstasy, said Sgt. J.D. Nelson said.

It was not known if any drugs were found at the home but chemicals were discovered, prompting deputies to call the Berkeley Fire Department's hazardous materials unit for assistance.

During the raid, three people were arrested on suspicion of possessing chemicals used to make narcotics and for various warrants, Nelson said.

The names of the three suspects were not immediately available.
