Bali Nine convict Scott Rush will be questioned about photos that apparently show him using drugs behind bars.
News Corp Australia newspapers ran the photos on Monday, which purport to show the 28-year-old smoking crack cocaine in Kerobokan prison.
The report quotes an unnamed source who says despite Rush’s claims to be clean, he regularly took meth, heroin and cocaine in the jail, which was “like a supermarket” for drugs.
Prison governor Farid Junaidi says he will study the photo and question Rush, who is serving life for the 2005 bid to bring 8kg of heroin from Bali to Australia.
He claimed to be leading a crackdown on contraband drugs, but admitted it was possible that some slipped through.
“Since the very beginning that I’ve been in charge here, I’ve started a war on drugs,” he said.
“Prisons have been bombarded by drug smuggling and it’s in big quantities, but we have managed to crack down on most of it.
“Certainly it’s possible that some still get away with it.”
The photos were allegedly taken in January, under the governor’s watch.
Rush – whose death sentence was commuted to a life sentence in 2011 – moved to Karangasem jail, in Bali’s east, in February.
He had been requesting the move for a long time, in order to be closer to a local “foster family” who were looking out for him.
Earlier this year, pictures of another Bali Nine inmate, Renae Lawrence, 37, were also investigated.
In the video footage, Lawrence claimed her former cell mate, Schapelle Corby, knowingly smuggled marijuana into Indonesia.
Bali officials determined the video couldn’t be used as evidence against Corby, who is now out on parole.
