MONROE -- Louisiana State police confirm that a local trooper has been arrested.
The arrest report says 42-year-old Ronald Thomas was arrested and charged with public payroll fraud, conspiracy to distribute cocaine, distribution of cocaine, malfeasance in office, and obstruction of justice.
Thomas was arrested without incident on Monday around 2 p.m. He has been booked into OCC with a bond of $250,000.
The arrest report says LSP Region 2 Criminal Investigation started an investigation in June 2012 into Thomas. The report says a co-defendant was also arrested.
The arrest report says the co-defendant confirmed to police during the investigation that he and Thomas distributed a large quantity of cocaine within Ouachita Parish over a two-year period.
That statement by the co-defendant confirmed to LSP investigators that Thomas was selling narcotics.
The arrest report also says that Thomas made a tip to the co-defendant that the State Police was investigating him, instructing persons involved to destroy the evidence and get rid of the money.
