Deputy Police Commissioner S. Jaykumar said the incident happened in February 2015 when two police officers signed a permit to take two prisoners out of the prison, using an excuse to investigate and then took them to the bar.
"We discovered the incident from the work diary in the police station and conducted an investigation," Mr. Jaykumar said.
Currently, the above two police officers have been suspended from work.

This is the latest scandal involving India's police sector. Previously, on March 21, four police officers were assigned to take a prisoner, a murderer, from prison in Jharkhand state to the hospital for a health check.
However, instead of going to the hospital, four police officers decided to drive 206 km to the red light area in Asansol town, West Bengal state.
West Bengal Police surrounded these four policemen during the brothel raid. Although the prisoner tried to escape, he later returned to the prison in Koderma city, Jharkhand state.
"We opened an investigation and suspended four police officers until further notice," said D.K Pandey, Chief Inspector of Jharkhand State Police.
