When Pitt and Jolie tried to leave the hotel, a security guard caught the photographer trying to take their photo, grabbed the man by his neck and verbally abused him.

Video of the incident was broadcast on India's CNN-IBN news channel, and the Hindustan Times newspaper identified the photographer as Sam Relph of Barcroft Media.

The newspaper reported that the security guard had shouted at photographers to stop shooting the couple and moved for Relph when he refused to put down his camera.

"He said if I took his pictures he would kill me," the Times quoted Relph as saying. "I couldn't breathe. He had his fingers on my windpipe and he knew what he was doing."

Two Indian journalists also complained that they too had been threatened by the same security guard, who was not identified in the report.

A weekend call to the office of Pitt's publicist in Beverly Hills, Calif., was not immediately returned.

The couple are reportedly scheduled on Monday to start shooting scenes for "A Mighty Heart," in which Jolie plays Pearl's widow, Mariane.

The movie is based on an adaptation of Mariane Pearl's book, "A Mighty Heart: The Brave Life and Death of My Husband Danny Pearl," and will be co-produced by Plan B, a production company founded by Pitt and his ex-wife, actress Jennifer Aniston.
