"We are now waiting (for that decision)," he said.
The request letter was concerning the transfer of Felix's detention location to a penitentiary that had a super-maximum security system, he explained.
One of the prisons that has such a security system is the Nusakambangan Prison.
"I cannot be sure when there will be a reply, but we sent the letter a month ago," he said.
While awaiting a reply, the Mataram detention center had imposed more stringent supervision on Felix, in a bid to thwart any attempt to escape.
"We check on him more intensively, every hour," he said.
He further explained that Felix had long been categorized as a high-risk convict, as he had attempted to escape from the prison twice.
Earlier, the West Nusa Tenggara High Court sentenced Felix to 19 years in prison and imposed a fine of Rp1 billion or another year in prison.
The French national attempted to smuggle in methamphetamine, amphetamine, ketamine, and methylendioximetamfetamine or MDMA, weighing a total of 2.98 kilograms.
He received €5,000 when smuggling the drugs into Lombok, West Nusa Tenggara, it was revealed. (INE)
