A RAID at a suspected “slap house” in Garden Grove resulted in the arrest of 21 persons on a variety of charges (GGPD photos).

Illegal gambling was the target of the Garden Grove Police Department’s Special Investigations Unit on Friday evening.

According to the GGPD, the SIU served a search warrant on a suspected “slap house” in the 13000 block of Cypress Street in Garden Grove. That’s just south of Garden Grove Boulevard, west of Nelson Street/Century Boulevard.

WEAPONS seized in the raid on Cypress Street in Garden Grove.

Officers arrested 21 people for outstanding warrants, illegal gambling, and/or obstructing an officer/resisting arrest.

Seized was $4,000 in cash, a Mac-10 firearm with a loaded high capacity magazine and suppressor, two loaded handguns and one dismantled assault rifle. Eight gambling machines were also located in a detached garage.

The term “slap house” refers to the video gambling machines that are played by banging with hands on the controls.

Assisting in the operation were the GGPD’s Community Impact Unit, Gang Suppression Unit, K-9 unit and patrol officers.
