Rajat, 21, sent the accomplice, Rishab, 23, to his maternal grandfather Ram Lal Miglan's house in Rohini's Sector 7 on Saturday afternoon.
Rishab gained entry to the house by posing as a technician out to check their cooking gas cylinder.
When the ageing Miglan and Rishab went to the kitchen, Rajat entered the house by wearing a helmet to avoid recognition by his grandparents. He tried to choke his 84-year-old grandmother Shakuntala Devi, who screamed for help, police said.
An alert Miglan caught hold of Rishab in the kitchen and also raised an alarm, after which neighbours rushed to their rescue and caught the two men.
Rajat admitted to police that he had hatched the robbery plan since his grandparents had received a handsome sum of money after selling their house.
The two bought a toy gun to threaten their intended victims. The toy gun was seized from them.
