A cash reward of Rs one lakh was announced for solving the Preet Vihar dacoity-cum-murder case, police said.
According to police, Badshah alias Kabir, a resident of Bagerhat in Bangladesh, along with his accomplice Mohd Tasleem, a resident of Bijnore in Uttar Pradesh, were arrested after months of investigation and intelligence generation.
The duo along with their other associates had broken into the house of a retired senior lawyer, Sumer Kumar Dutta, in Preet Vihar on April 25 and smothered his son Animesh before fleeing away with cash and jewellery.
"Efforts are on to recover the looted booty and nab other members of the gang," said Deputy Commissioner of Police (East) Ajay Kumar.
