The accused, identified as Purkha Ram, was nabbed yesterday and was being interrogated, Jaisalmer Kotwali SHO Derawar Singh said.
Ram was a displaced Pakistani Hindu migrant and had been renewing his visa, Singh said, adding that the accused also had an Aadhaar card with a residential address in Sri Ganganagar district.
Ram has been living in India for over a decade and investigators were looking into how he managed to get an Aadhaar card, the SHO said.
