HOUSTON -

A Houston woman was arrested after police said she sent a text message about a bomb to a coworker when she was released from jury duty.

Court documents showed Cynthia Ann Creed, of Deer Park, sent the message to her coworker, Janie Ibarra, on Tuesday morning.

It said that there was a bomb at the courthouse at 1201 Congress in Houston and that she needed to notify law enforcement. Houston police and the Harris County Constable's Office Precinct 1 responded. They evacuated the building, including the jury pool area.

Deputies and police then visually inspected the entire building and used bomb sniffing dogs. About 13 minutes after the original message was sent, Ibarra got another text from Creed that said she was just kidding. Ibarra turned over Creed's phone number and information.

Deputies tried several times to contact Creed by phone, but she kept hanging up on them. Creed finally admitted to sending the text, officials said. She told investigators that it was a joke and that she was sorry for the false threat.

"We take those things seriously," Precinct 1 Constable J.C. Mosier said. "Courthouses and airports, and those types of places, based on things that have happened in our past, they're not places where you make jokes."

Creed now faces false alarm or report charges.

"Even she couldn't tell me why she did it," Mosier said. "She just said, 'I just don't know. I'm just so stupid.'"

Creed posted bond and was released from jail.

"I felt bad for Ms Creed. She's a nice lady. I don't know what made her do this," Mosier said.
