Raju Sonkar was working in a ration shop in Mumbai for the last 10 years. His cousin, Shivnath, was a cook in the house of a senior citizen at Khar with a fake identity.
Sonkar, along with his four accomplices, Hasim, Shivnath, Kallu and Santosh, robbed the house of Shivnath's employer on August 31.
While committing the robbery, they selected a time when the elderly woman was alone at home and her family members, including her husband, were away, the police said.
Sonkar had taken a flight from Mumbai to Delhi on September 1 and was staying at a relative's place in Daryaganj here, said Deputy Commissioner of Police (North) Jatin Narwal.
