OAKLAND -- Marijuana and hashish with a street value of more than $100,000 was seized and three people arrested Wednesday afternoon after police raided a North Oakland business.

The raid happened about 12:30 p.m. in the 700 block of 55th Street, not far from Children's Hospital Oakland.

Police had been tipped about a week ago that marijuana was being sold illegally at the site, which claimed to be a gift store. Police said the business had no documentation that would allow them to sell marijuana legally.

Officers from Crime Reduction Team 2 put the business under surveillance and gathered evidence to obtain a search warrant, which was served Wednesday, said the team's supervisor, Sgt. Curtis Worcester.

Worcester said police seized at least 30 pounds of packaged marijuana ready for sale and several ounces of hashish. Police estimated the street value of the marijuana to be more than $100,000 and the hashish to be at least $10,000.

Police said the two owners of the business -- a 27-year-old San Francisco man and a 29-year-old Rodeo man -- were arrested along with a 28-year-old Richmond man allegedly employed as an enforcer. The Richmond man tried to hide a pistol with a laser sight but it was recovered. The three were arrested on suspicion of marijuana and hashish for sale and the Richmond man also for being a felon in possession of a firearm. Their names were not released.

Worcester said customers, some of whom had legitimate medical marijuana use cards and others who did not, could buy items including custom-rolled joints, paraphernalia and sizable amounts of weed.

Police estimated the business had been operation at least since June and was doing $1,000 a day in sales if not more. Police were trying to determine where the suspects got the marijuana.
