On Thursday morning, more than 200 local and federal law enforcement officers served 40 search warrants and 43 arrest warrants in Alameda, Contra Costa, Marin and Sacramento counties. They arrested 18 alleged gang members and seized eight firearms. Agents also seized large quantities of cocaine and marijuana with a total street value of about $100,000 and more than $17,000 in cash.
