Phone found after prisoner's bum rang

A Sri Lankan prisoner who tried to hide a mobile phone was caught when guards heard his backside ringing.

The 58-year-old convict was admitted to the national hospital in Colombo where doctors later retrieved the handset from his bottom.

"The man had concealed the phone inside his person," the official said, asking not to be named.

"Unfortunately for him, the phone rang at the wrong time and guards knew he had a phone at the wrong end."

He said the man was in hospital for two days but was discharged and sent back to prison after the mobile phone was removed.

The prisoner was serving a 10-year sentence for theft at the high security Welikada jail in the capital.
