Geoffrey McGann, 49, of Rancho Palos Verdes was taken into custody Thursday night after he tried to pass through airport security with an ornate watch that had switches, wires and fuses, according to Sgt. J.D. Nelson, a spokesman for the Alameda County Sheriff's Department. A bomb squad arrived within five minutes and determined there were no explosive materials in the watch. McGann was charged with possessing materials to make an explosive device.

Police contacted the State Law Enforcement Division’s newly formed Joint Enforcement Team (JET) that targets drug organizations and violent crime activities across the state. The team confirmed the grow facility and, along with the U.S. Drug Enforcement Agency, investigated and seized lab equipment and large quantities of mushrooms in various growth stages.
