A total of 19 mobile phones were reported to have been recovered from inside three prisoners after they set off metal detector during a prison check.
The prisoners upon further check were found to have the mobile phones inside of their bodies and the group were made to undergo X-ray which further proved the presence of the contraband in their bodies.
One of the prisoners at the Presidente Bernardes jail in the Brazilian state of Sao Paulo had five small mobile phones in his rear, and another was found to have four meshed into his anus.
The third person was reported to have had a total of ten mobile phones in his stomach, along with headphones.
The two prisoners with the phones forced into their anal region did not need surgery for extraction while the man with ten phones in his stomach had to undergo surgery to remove them.
Police operatives have since seized the devices and the inmates have been subjected to further investigations.
