A Graniteville bank robber could be heading back to prison after he allegedly committed a substantial number of violations of his supervised release.

Thomas R. Washington, 46, was sentenced to five years, 10 months in prison followed by three years of supervised release for the 2007 attack on Security Federal Bank in Graniteville.

Washington was released from federal prison in April 2012, but could return after he was arrested for violating his supervision by using illicit substances, new criminal conduct, failure to participate in substance abuse counseling and failure to report a change of employment or residence.

On Oct. 17, Washington was arrested and charged with criminal domestic violence by the Columbia Police Department.

According to court documents, he tested positive for cocaine use on Oct. 22 and 24; Nov. 7, 8 and 15; and Dec. 4. He missed urinalysis testing on Dec. 10, 20 and 27, and Jan. 3 and 7. As part of his counseling, Washington missed sessions on Dec. 18, 20 and 27, and Jan. 7. Also, on Jan. 16, he quit his job with a fast-food restaurant and left his residence.

Each of these incidents could be considered a violation on their own. He now faces spending the remainder of his supervised release in prison.

Washington’s crime was noted, at the time, for his use of an unwitting taxi to pick him up and play getaway driver. Authorities said Washington hired a taxi driver to take him from a motel off Gordon Highway in Augusta to the Security Federal in Graniteville. As the cab waited outside, Washington walked inside at about 9:15 a.m. and demanded money from a teller. He was handed cash, but spilled it as he fled the bank and into the cab. However, before he escaped, he was spotted by a member of the Graniteville Fire Department. Fire Chief Phil Napier and another firefighter followed the taxi and radioed the Aiken County Sheriff’s Office. Soon afterward, Washington was arrested.
