OKLAHOMA CITY - It was Colonial Day at the State Capitol like no other.
Students came to experience history but got another lesson instead.
A bomb threat led to an evacuation around 10:30 a.m. Friday.
OHP Trooper Betsy Randolph said it came from a telephone call.
"Oklahoma City 911 Dispatch received a call from a female who advised that multiple bombs were going off at 10:30 a.m.," she said. "One of the bombs was at the governor's mansion, the other was at an undisclosed location."
Although the Capitol was not named as a specific target, the governor was there and decided to evacuate the Capitol and not take any chances.
Randolph said bomb techs went to work.
"So our guys got in and searched the building," she said. "They do what is called a 'sweep.' They did that both at the governor's mansion and here at the State Capitol complex."
Chaperones like Tiffany Bolding said the students handled the evacuation very well.
"The kids evacuated great; everyone was really calm," Bolding said. "We went across the street and the buses came around and they got on the buses to stay warm."
Patty Mellow, the Colonial Day organizer, said a bomb threat did not put an end to learning.
"And the stories went on," Mellow said. "We had Patrick Henry still here getting on the bus and talking about our foundation and what happened in America."
Nothing was found at the mansion or Capitol and the students went back inside to continue a day of "hands-on" learning.
Police said they've identified the woman who made the phone calls.
They said she is believed to be in her 20s and could face charges.
