An Australian prisoner who denied having a cellphone has produced evidence to the contrary — via his rectum.

The Triple murderer is in a Supermax facility and has repeatedly breached bans on owning cellphones, including at one point updating his Facebook status.

After the latest handset sighting, the man denied having a handset even after staff, having failed to find it in a search, used a bodyscan machine and spotted it inside him. He instead claimed it was metal left inside him after surgery.

Prison staff then put him in an isolation cell under close observation and waited for the evidence to emerge. Although Georgiou went on hunger strike to delay the inevitable, the handset finally appeared after 12 days.

Sadly officials haven’t revealed what make or model the handset was, nor if the experience has given any insight into its battery life.
