A prison guard was indicted Wednesday on a federal charge of accepting bribes to smuggle tobacco to inmates at the U.S. Penitentiary in Leavenworth.

U.S. Attorney Barry Grissom says Michael Harston, 52, Kansas City, Mo., was charged with one count of conspiracy to commit bribery and four counts of accepting bribes. The indictment alleges that from October 2013 to August 2014 Harston took bribes to carry tobacco, which is contraband, into the penitentiary.

The indictment alleges payment was made via wire transfers from inmates’ relatives. Harston was caught on video surveillance in the process of distributing tobacco to inmates.

If convicted, he faces a maximum penalty of five years in federal prison and a fine up to $250,000 on the conspiracy charge, and a maximum penalty of 15 years and a fine up to $250,000 on each of the bribery counts.

The FBI investigated. Special Assistant U.S. Attorney Leena Ramana is prosecuting.
