'One of the accused, Sunil, works as an auto driver, while his accomplice, Vikas, is a tailor. Both wanted to earn quick money to buy expensive gifts for their family for Raksha Bandhan,' the official said.

Gupta, a supplier of Nova brand tea, was ferrying tea in the tempo pick-up when the incident occurred. He used to visit shops in south and southeast Delhi to deliver the tea and collect the sale money.

When his vehicle slowed down while climbing the Modi Mill flyover towards Nehru Place, the robbers threw chilly powder in his eyes and snatched his money bag containing Rs.34,370 at knife point,' the police official added.
