He used to take Mohak,a class 12 pass-out,along with him and the duo got acquainted with the family.
Subhash Chandra,IG (Lucknow),said Shiv Kumars family needed money after he developed some kidney problem. It was then Mohak and Mayank planned to rob Mehras house. They knew that the couple lived alone and their only daughter used to stay in Delhi.
Police said the brothers accompanied with their two friends Vijendra and Shiva reached Mehras house in a car owned by Shiv Kumar on the afternoon of April 14. While Mayank and Shiva stayed outside to keep a watch,Mohak and Vijendra entered the house. As Mohak was known to the family,they let him in. They were also served two glasses of water by Lata. Mohak and Vijendra attacked Mehra and his wife with knives, said Chandra.
They took jewellery and some cash from an almirah which was not locked. Chandra said police had recovered about 2 kg gold jewellery which Mayank had given to his friend Ritu Garg to keep saying it belonged to his mother.
Chandra said Garg deposited the jewellery in a Punjab and Sindh Bank locker in Naka. He said the car used for going to Mehras house has also been recovered.
