2 prison guards and a former guard charged with beating inmate

SBI agents arrested three prison employees Wednesday accused of beating an inmate while working at a maximum-security prison in Greene County.
   
Investigators say Gregory Beck, Terry Bell and Steve Bostick used force on an inmate at Maury Correctional Institution back in March of 2008.
   
Beck resigned from his captain position last July.
 
Bell and Bostick still work at Maury.
   
They have been suspended pending the investigation.
