MARANA, Ariz. -- Authorities said a device found under a car at a Marana restaurant over the weekend was a bomb.
The federal Bureau of Alcohol, Tobacco, Firearms and Explosives said the device found Sunday under a car at a Hooters restaurant was an improvised explosives device.
Police were called late Sunday afternoon by an unidentified Tucson man who spotted the device after leaving the restaurant and returning to his car.
Police evacuated 200 people from the restaurant and a nearby bowling alley while they investigated. The Pima County regional bomb squad then neutralized the device.
Bureau spokesman Tom Manigan said the device has been sent to a bureau laboratory for detailed analysis, including DNA testing.
No arrests have been made.
