Guwahati, April 6 (IANS): Popular Assamese singer Zubeen Garg was once again embroiled in controversy here -- this time by wielding a 'gun' during a musical performance, threatening the audience not to leave otherwise he would shoot them.

The singer of 'Ya Ali' fame from "Gangster" movie, was performing at an ongoing three-day cultural and musical extravaganza at the veterinary college ground in Guwahati's Khanapara area on Sunday night.

"I'll sing with this gun now. It's not fake, it's real. Don't go away or I'll shoot you," he said in the middle of his performance while brandishing a pistol in his hand.

Garg held the gun for some time as he resumed singing. Soon police arrived at the event only to find that it was a toy pistol.

"We were informed about the incident last night at the Khanapara play ground. Our personnel frisked the singer but they found only a toy gun with him," said Deputy Commissioner of Guwahati East Police District H.K. Das.

"Zubeen later told us that he came to the programme from a film shoot and he brought the toy gun from the shooting. No case was registered against him as no one had lodged any complaint in this regard," the official added.

Off and on Zubeen has been having a brush with controversy for one reason or the other. In one of the incidents in 2013, he defied a diktat of the Ulfa militants not to sing Hindi songs during Bihu functions.
