Randy Smith’s resignation was part of plea deal after attack on podcaster Bobby Couvillion at a Madisonville restaurant

A suburban New Orleans sheriff who had held one of his community’s most prominent political offices for a decade has retired shortly after pleading guilty to battering a podcaster who often criticized him.

Randy Smith, 61, also agreed to serve more than a year of probation after admitting to a late May beating at a steakhouse where he had bought 18 alcoholic beverages on his tab on a Friday afternoon – which all but halted his four-decade policing career.

Smith had been sworn in as the elected sheriff of St Tammany parish, Louisiana, on 1 July 2016, succeeding a predecessor who eventually pleaded guilty to federal bribery charges and was separately convicted of serial child sexual molestation.
