CHATTANOOGA, Tenn. (AP) - The Hamilton County Sheriff says he is asking the Tennessee Bureau of Investigation to look into whether he violated procedure by giving a car back to its owner after it was seized during the drug arrest of the woman's son.

Marcia Tenenbaum told the Chattanooga Times Free Press (http://bitly.com/VANz8T) she phoned Sheriff Jim Hammond after her son was arrested in April for having 15 ounces of marijuana in Tenenbaum's Lincoln Towncar.

Tenenbaum said she knew the sheriff because they were classmates at the University of Tennessee at Chattanooga in the criminal justice program.

The sheriff arranged to have the car returned to her.

Hammond told the paper he does not remember Tennenbaum from school. He said turned the issued over to the narcotics division but there was a paperwork error.
