Maharashtra Home Minister Dilip Walse Patil on Sunday police teams from four-five States were working together on the case of murder of popular singer and Congress leader Sidhu Moose Wala in Punjab last month and the Maharashtra Anti-Terrorism Squad (ATS) was also keeping an eye on it.
The Delhi Police recently said gangster Lawrence Bishnoi was the mastermind behind the murder and that they had identified six shooters allegedly involved in the killing of Moosewala. The singer's death was an organised and brazen killing, the Delhi police had said.
Investigators had also revealed that Mahakal alias Siddhesh Kamble, arrested by Pune rural police in Maharashtra recently, knew that Moosewala was going to be murdered, and was in touch with gangster Vikram Brar a week before the killing.
Kamble is an alleged member of the Lawrence Bishnoi gang, which is said to be behind Moosewala's murder.
Brar is a close aide of gangster Lawrence Bishnoi, who is currently in the Delhi Police's custody.
