The victim, identified as Rakesh Kumar Jain, was returning home on his two-wheeler when the two accused, who were following him, stopped him and asked him to give the keys of the cash box of his daily earnings, the official said.
Jain was involved in the business of exchange of old notes.
The victim was rushed to the GTB Hospital, where he was declared brought dead, they said.
The accused fled from the spot without taking the box, they added.
The victim had been attacked and robbed earlier also and the police are probing whether those men who were arrested earlier were involved in this incident.
