A prisoner (in Sri Lanka) tried to hide his cell phone in his anus during a routine search of his cell. 

He was caught when guards heard a ring coming from his rear-end.

The Convict had to be admitted to the hospital. An X-ray showed a large cellular device lodged right under his spine and between his hip bones. Docs later retrieved the handset from his rectum.

The prisoner was in the hospital for two days and sent back to prison where he is serving a 10-year term for theft.
