Canada-based gangster Goldy Brar, an associate of Bishnoi, earlier claimed responsibility for killing singer-politician Sidhu Moosewala.
The Punjab Police on Sunday said Punjabi singer Sidhu Moosewala's killing appeared to be a fallout of an inter-gang rivalry.
Earlier, former Punjab Congress president Navjot Singh Sidhu had approached the Supreme Court seeking a few week to surrender to serve the imprisonment.
