BUFFALO, N.Y. (WIVB) — A former Buffalo police officer was sentenced to three months in prison for a misdemeanor civil rights violation.

Robert Eloff, 41, faced up to one year in jail after pleading guilty to deprivation of rights under color of law in June. As part of his plea deal, Eloff resigned from the police department.

While off-duty, Eloff was working security at Molly’s Pub back in May of 2014. During one night, a bar manager, Jeffrey Basil, pushed William Sager, Jr. down a flight of stairs. This turned out to be fatal for Sager.

A friend of Sager’s, Donald Hall, was wrongfully handcuffed and arrested by Eloff on a charge of trespassing, according to prosecutors.

Eloff submitted a letter apologizing for what had happened before his sentencing.

In addition to time in prison, Eloff was also sentenced to three months of home confinement.MORE | See what Eloff said in the letter here.
