The Tulsa County Sheriff's Office confirmed changes are being made to the reserve deputy program.
Wednesday, Sheriff Stanley Glanz said the department made a policy change saying reserve deputies are no longer allowed to patrol by themselves.
It was also confirmed that the reserve program is being postponed while a records audit of each reserve training file is taking place.
Reserve deputies will still be utilized as long as they are partnered with a certified deputy, the sheriff's office said.
The reserve program has come under fire lately as questions regarding Bob Bates' training have surfaced.
A 2009 report reveals Bates received special treatment and equipped his personal vehicle as a police car.

It also says the deputy overseeing Bates' training says he signed off that Bates had 150 hours more training than he actually had completed.
Bates has been charged with second degree manslaughter in the April 2 shooting death of suspect Eric Harris.
