SAN JOSE -- Police detonated a live pipe bomb early Thursday morning near North First Street and Matrix Boulevard, adjacent to Highway 101, after a car was pulled over that turned out to have a suspicious device.

Members of the department's special operations unit pulled the car over for a violation at 8:48 p.m. and conducted a search of the vehicle, according to San Jose police Sgt. Jason Dwyer,

Nobody was injured or evacuated during the incident.

A man was taken into custody, Dwyer said. He did not offer any specifics about the arrest.

Officers discovered the device and contacted the bomb squad. Dwyer said streets are closed and traffic in the area will be affected while the bomb unit works, which is expected to take three or four hours.

No information about the driver was released. Nearby businesses have been advised about the incident and told to "evacuate at their discretion," according to Dwyer.

Police did not immediately release any more information, citing an on-going investigation.
