BATON ROUGE - Police and federal drug authorities arrested a Baton Rouge doctor on charges he continued to prescribe drugs to people after he was suspended from dispensing narcotics.

Baton Rouge Police said Dr. Randy Lamartiniere, 57, was arrested by members of the Tactical Diversion Squad - Group 29, which includes members of BRPD, DEA, LSP, EBRSO and the Iberville Parish Sheriff's Office.

Investigators said the Louisiana State Board of Medical Examiners suspended Dr. Lamartiniere last year from prescribing, dispensing or administering drugs to people after Dec. 30, 2015. Investigators said they learned Lamartiniere continued to give out such drugs, and those prescriptions were filled at various locations around the Baton Rouge area.

Narcotics agents said in all, Lamartiniere prescribed more than 3,500 doses of narcotics which were on the Controlled Dangerous Substance list. Those prescriptions were either given or filled between Jan. 4 and 5, according to authorities.

A post on Dr. Lamartiniere's Facebook page in October said he would no longer be taking on new patients, or handling pain management services for patients. It also said he planned to take on new patients starting Jan. 4.

Investigators arrested Lamartiniere and booked him into the East Baton Rouge Parish jail Tuesday.
