Lee said all of the suspects surrendered peacefully, but would not give details as to the amounts of methamphetamine and cocaine that were seized.

According to Lee, a Mexican drug cartel has a presence in the East Bay. He described this incident as part of a larger “organized crime, gang-affiliated type of event”.

Authorities wanted to disrupt the flow of drugs that are controlled by the drug cartel. Lee said Mexican drug pushers routinely traffic drugs up and down Highway 101 and Highway 5.
