The Indian government is awaiting details about the arrests of three Indian nationals in Canada for the murder of Sikh separatist leader Hardeep Singh Nijjar, external affair minister S Jaishankar has said, reported The Hindu on Sunday.

Jaishankar also claimed that Canada has not provided any evidence of the Indian government’s involvement in Nijjar’s assassination despite repeated requests, according to the newspaper.

“I came across news yesterday night that three people have been arrested, apparently Indians of some kind of gang background,” The Hindu quoted Jaishankar as saying. “We have to wait for police to tell us more.”

On Friday, the Royal Canadian Mounted Police had arrested Karanpreet Singh, Kamalpreet Singh and Karan Brar from Edmonton, Alberta, in connection with the case. They have been charged with first-degree murder and conspiracy. They are all in their twenties.

The three had been living in Canada for three to five years, according to police officials.
