A 24-year-old St. Petersburg man said he was impaired Tuesday when he left a voicemail message threatening to blow up a sheriff's sergeant, according to the Pinellas County Sheriff's Office.

When detectives questioned Daniel Lee Harris, the agency said he told them he doesn't even know the sergeant — he was just trying to call his probation officer.

Harris said the whole thing happened "because I'm an idiot," according to the arrest report. He faces a charge of threatening to discharge a destructive device.

The call was made at about 1:12 p.m. to the voicemail of Pinellas sheriff's Sgt. Richard Bailey, 57, who works in the agency's misdemeanor probation unit.

"Hey Sarge, I hope you like your kids. Gotta bomb coming," said the male caller. The sheriff's criminal intelligence unit was told of the threat at about 3:45 p.m. Detectives determined that the call came from Harris through various "investigative techniques," according to the Sheriff's Office.

The Sheriff's Office said it sent dogs to search Bailey's home for explosive devices but found none. Harris said he was trying to get in touch with his probation officer but somehow got Bailey's voicemail, according to the Sheriff's Office. He did not know the sergeant.

Harris, who also violated his probation from a charge of petty theft, was being held without bail in the Pinellas County jail.
