Employees discovered the robbery when they opened the showroom the next morning.

The robbers had also spilt chilli power in the shop to confuse the police dogs, PTI reported.

Police Commissioner A Amalraj said that local police officials have visited the spot to look for clues. "We have got some basic information. We have formed several teams to arrest the culprits," he said.
