Rahul and his accomplices broke into the shop in Prem Nagar on the night of March 24, police said.
The gang came in a stolen car and stole 3 LED TVs and 110 mobile phones after breaking the shutters of the shop, police said.
A PCR van on patrol duty spotted the gang as they attempted to make a getaway. A passerby who was trying to take out his car blocked the thieves' way.
A country-made pistol and the stolen booty was recovered from Rahul's possession.
