NACOGDOCHES, TX (KTRE) - Nacogdoches County Sheriff's deputies arrested a 52-year-old Rusk County man Tuesday morning after he allegedly sent numerous text messages in which he threatened to blow up the courthouse and the sheriff's office and harm the sheriff.

Calvin Polk is still being held in the Nacogdoches County Jail on two third-degree felony charges of retaliation. Collectively, his bail has been set at $30,000.

According to a press release, Sheriff Jason Bridges started receiving personal text messages on his private phone about two weeks ago from an unidentified caller.

"The messages were random and it appeared the caller had the wrong number," the press release stated. "The caller was advised several times to stop texting."

At approximately 5 a.m. Tuesday morning, the text messages to Bridges started becoming "very threatening." A threat was made to use a bomb at the sheriff's office.

The press release stated that at about the same time, the sheriff's office received a call from another Nacogdoches citizen who was also receiving text messages from the same number. The citizen, a retired police officer, did not recognize the number and was not collected to the person who sent the texts.

Numerous threatening messages were allegedly sent to the retired police officer. According to the affidavit stated that the caller was going to blow up the courthouse and kill the sheriff.

Within an hour of when NCSO deputies started investigating the alleged threatening messages, they had identified Polk and learned that he lives in Rusk County. With the assistance of Rusk County law enforcement officials, the deputies went to Polk's residence in the 19000 block of County Road 4235, where they found the suspect and his phone.

Deputies verified that the text messages had been sent from Polk's phone, according to the press release.

According to the press release, Polk was upset with law enforcement because a family member has a pending criminal case.
