A kitchen supervisor at a jail in San Antonio was arrested Tuesday, accused of attempting to smuggle in meth and alcohol to inmates in exchange for money.

Ray Alexander Barr, an employee of the Central Texas Detention Facility in downtown San Antonio, asked several inmates if they wanted contraband smuggled into the prison, according to the U.S. attorney’s office.

Barr reached an agreement with at least one inmate to smuggle meth and alcohol into the jail, authorities said. He was arrested immediately after he accepted payment from the inmate, but before he could deliver the drugs and alcohol, according to the U.S. attorney’s office.

If convicted, he faces up to 20 years in federal prison and up to a $250,000 fine.
