The Indian underworld gang run by Chhota Rajan could be behind Sunday's killing of media entrepreneur Jamim Shah, Nepali police said.

The role of international criminals has been established and the killers will soon be nabbed, local media The Kathmandu Post reported Tuesday, citing Ganesh K. C., chief of Metropolitan Police, Kathmandu.

"Shah's murder has been carried out by someone from the Chhota Rajan gang," Ganesh said, adding that the phone calls made to Cable Television Association and Avenues TV on Monday and interrogations of more than a dozen people indicate that the killers had arrived in Kathmandu on a 'mission' to kill Shah.

Bharat Nepali, an aide of Chhota Rajan, called the association and Avenues TV claimed responsibility for Shah's killing, alleging that Shah was involved in anti-Indian activities, police informed on Monday.

Forty-seven-year-old Shah, who was chairman of Space Time Network Pvt Ltd and Channel Nepal Television, was shot by two unidentified men on a motorcycle at Lazimpat of Kathmandu, and succumbed to bullet injuries at the Tribhuvan University Teaching Hospital on Sunday.
