Deputies said 53-year-old Stephen Harry Grimm was arrested by the Polk County Sheriff's Office on October 5, for violating his probation on a DUI charge. 

Deputies said Grimm was sentenced to 180 days in jail and had been housed in a cell in the jail in Frostproof since his sentencing.  

Grimm violated his probation by failing to provide to his probation officer proof of enrollment in a DUI program, and for reporting to his probation office drunk deputies said.

Deputies said at approximately 5:00 p.m. on Friday, Grimm was observed by detention deputies in his cell with no issues.  \
