Interestingly, the cops were undergoing training to handle 'emergency situations'.
The sale and consumption of liquor is prohibited in Gujarat but not in Diu, which is about 225 km from here.
"Over 12 trainee policemen were undergoing training to handle any emergency situation at the Rajkot police headquarters in Mavdi area," Superintendent of Police, Rajkot Rural, Antrip Sood said today.
"A video went viral on WhatsApp showing the van parked outside a hotel in Diu and the policemen consuming liquor inside," he said.
Deputy Superintendent of Police Shruti Mehta is conducting the inquiry and is likely to submit her report within a day, sources at the Rajkot rural police station said.
A probe is also being conducted to find out how they reached Diu in the police vehicle when they were undergoing training in Rajkot, the sources added.
