Adrian Rowland, 53, a father of three children, was having a video chat to his girlfriend, Julie Zalinski, when he produced a knife and killed himself as she watched live over the internet.

Rowland worked for an engineering firm in Woodley, Berkshire and was in India seeking business opportunities, The Sun reported.

Zalinski, who works for the same firm, dialled British emergency number 999, and local policemen contacted Indian authorities via the Foreign Office.

The report, however, did not mention where the man was staying in India.

The couple reportedly was having difficulties over their relationship.

A friend of the pair said: “I heard they were having a discussion about their future together. He killed himself in front of her as she watched over the camera. It must have been the most horrendous thing imaginable. She could see he had cut his throat but could not do anything to stop him,” a friend said.

It is expected his body will be flown back to Britain and an inquest held in Berkshire.
