Three bandits, said to be Latin Americans, robbed a supermarket in the Barrackpore area on Tuesday night.
A police corporal who walked in on the robbery was also robbed.
The three suspects entered the Wishful Company Limited Supermarket at New Colonial Road, Barrackpore, around 7pm, wearing dark clothing, masks and armed with guns.
The men then proceeded to rob a supermarket worker of cash.
While the robbery was in progress, a police officer attached to the South Western Division, entered the supermarket and a gun was placed at his waist.
He was robbed of a bag containing his TTPS firearm, police Identification card and badge, and cash and other items.
The bandits then escaped.
Investigations are currently underway.
