The Howrah Government Railway Police (GRP), on a complaint by co-passengers, arrested the men after they de-boarded the train at the station.

The constables, identified as Kulwant Singh and Harjeet Singh, were travelling in the Kalka Mail from Delhi. The complainants told the GRP that since late Monday evening, the duo was drinking and displayed uncontrolled behaviour. Passengers said they tried to file a complaint against the constables with the GRP at Mughalsarai station around 9:30 pm on Monday. The officers at the station, however, refused to register a complaint, they alleged.

The complainants, along with other police personnel on duty in the same compartment, said the constables vomitted and relieved themselves on the luggage of the passengers.
