Explosives experts defused a homemade bomb found in the backseat of a car early Friday after the driver was stopped for speeding in this eastern Los Angeles suburb, authorities said.
The bomb was defused safely, but several industrial businesses in the area were evacuated and a main boulevard was closed for more than three hours.
After the driver was pulled over around 5 a.m., deputies "observed a package in the rear of the vehicle with wires coming out of it," Los Angeles County Sheriff's Sgt. Don Manumaleuna said.
The sheriff's arson-explosives detail described the package as an "improvised explosive device," Manumaleuna said.
The driver, whose identity was not immediately released, was being held for questioning.
