While the incidents took place at intervals, within the jurisdiction of three different police stations, the modus operandi was the same, they said.
In an incident in Kavi Nagar area, two men on a motorcycle forcibly took away BSP district president Ram Prashad Pradhan's chain after stopping him on the pretence of asking directions while he was returning home after a morning walk .
In another case, the chain of journalist Neetu, a resident of Indirapuram, was snatched near Vaishali metro station.
Similarly, three men approached Dr Rajiv, a resident of Lohia Nagar, when he was heading home from a local market and looted his gold chain.
