A respected professor of psychology at Texas Christian University who's been in a Tarrant County Jail cell for a week allegedly violated an order from the college provost to stop sending threatening emails to employees, and then called him a "sexist pig."

Two days later, Charles Fredrick Bond allegedly e-mailed two school officials to say he "would bring a gun to the campus of Texas Christian University." He also wrote he would "spit" in the face of a psychology professor, according to the affidavit, the Associated Press reported.

Bond, 53, was arrested at his Fort Worth home last Friday after campus police obtained a “harassment” warrant, according to the Star-Telegram newspaper. TCU police, assisted by Ft. Worth police, went to Bond’s home, where he was arrested apparently without incident.

"We went in with the knowledge from the warrant affidavit that [Bond] may have a gun, namely an Uzi, that he had hinted to bringing on campus," the police report said, according to the newspaper. Bond "was allowed to put on some clothes and use the restroom before being placed in handcuffs."

Ft. Worth police later charged Bond with making a terrorist threat, a class B misdemeanor punishable if convicted by up to 180 days in prison.

None of the people Bond allegedly threatened shared any notable similarities other than their association with the school, Tracy Syler-Jones, associate vice chancellor for marketing and communication for TCU, told FOXNews.com.

Syler-Jones said she was not allowed to go into detail about the nature of the alleged threats.

A psychologist was expected to evaluate Bond on Thursday, the Star-Telegram reported. A hearing was scheduled for Tuesday to determine conditions for bail.

TCU officials released a statement Wednesday that said Bond “exhibited extremely inappropriate conduct and made threatening remarks to some campus members. Because safety is a top priority at this institution, the TCU Police Department took action and prepared an arrest warrant for Dr. Bond.”

Bond was placed on administrative leave and is not allowed back on campus, the statement said.

Bond's lawyer, Tim Clancy, said his client has an exemplary record, no criminal history and is innocent.

“We feel he is not a threat to himself or the community, and we are optimistic that the case will be resolved,” Clancy said.
