Washington: Biswanth Halder, the Indian-origin gunman who is accused of killing one American student in the prestigious Case Western Reserve University in Cleveland, Ohio, was a graduate student and later an employee of the same University and had military training from Indian Army before he went to US.

Halder, 62, who in his online resume says he had military training with the Indian Army before coming to US, nursed a grudge against an employee of the University who apparently had him dismissed. Halder had filed an appeal against his removal but the appeal was dismissed.

The man, armed with two handguns, held police at bay for seven hours in the University's modernistic, shiny, swirling building filled with twisting corridors that complicated his being shot or overpowered by the police.

Halder wore a bullet-proof vest and a wig glued on "a kind of World War II Army helmet" as he walked the halls of the University's Peter B Lewis building which houses the Business School, and fired hundreds of rounds, Police Chief Edward Lohn said. "There is a trail of blood throughout. It was a cat- and-mouse game," Lohn said.

Norman Wallace, a 30-year-old graduate student, was killed in the rampage.

An Indian student at the University was among those at whom he fired shots but missed. The two injured, a 32-year-old man and a 46-year-old woman, were released from the hospital on May 10, authorities said.
