OKLAHOMA CITY -- Oklahoma City police ordered the evacuation of City Hall and nearby buildings Wednesday morning after a stolen U-Haul truck was discovered outside the building.
Police Capt. Dexter Nelson said a five- to six-block area was cordoned off Wednesday while the city's fire department and bomb squad investigated the truck.
Nelson said the evacuations were ordered as a precaution and that there was no evidence that suggested there might be a bomb in the truck.
Just after 10 a.m. officials gave the all clear when the U-Haul was found to be empty.
Nelson said Oklahoma has always been a "hyper-vigilant" state after the Oklahoma City bombing, and that Monday's bombings at the Boston Marathon gave 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.
