OKLAHOMA CITY (AP) - Oklahoma City police have ordered the evacuation of City Hall and nearby buildings after a stolen U-Haul truck was discovered outside the building.
    
Police Capt. Dexter Nelson says a five- to six-block area was cordoned off Wednesday while the city's fire department and bomb squad investigate the truck.
    
Nelson says the evacuations were ordered as a precaution and that there was no evidence that suggested there might be a bomb in the truck.
    
Nelson says Oklahoma has always been a "hyper-vigilant" state after the Oklahoma City bombing, and that Monday's bombings at the Boston Marathon give even more reason for caution.
    
On April 19, 1995, Timothy McVeigh detonated explosives packed into a yellow Ryder rental truck, killing 168 people in and near the Oklahoma City federal building.
