Town Deputy Superintendent of Police Ashish Anand said an excise department team visited Kazi Mohammadpur police station today following complaints received late last night.
The team found the officer-in-charge Rameshwar Singh in an inebriated state and tried to catch him. There was pushing and shoving and Singh even tried to run away when he was being taken for medical test to ascertain that he had consumed liquor, he said.
Other policemen of the police station gave him a hot chase and nabbed him, Anand added.
Total prohibition is in force in Bihar since April last year.
