A Brentwood man was sentenced to four months house arrest and three years probation today for impersonating a federal prosecutor.

Jerry A. Pratt, 34, pretended to be Assistant U.S. Attorney Ross Lenhardt to try to get a promotion with Comcast in December 2006. He made phone calls pretending to be Mr. Lenhardt, and claiming that Mr. Pratt had a clean criminal record.

"What Mr. Pratt did was incredibly stupid, incredibly foolish," said Stephen Israel, his defense attorney.

Mr. Pratt told U.S. District Judge David S. Cercone that he didn't realize what he'd done was a crime.

The judge told him that was no excuse.

But, Judge Cercone also told Mr. Pratt he didn't feel the man should lose his job as an assistant property manager over what he'd done.
