Daniel, who hails from Kerala, had been working in the hospital since 2007. He is survived by his wife Geeta George, who lived with him in the United Arab Emirates, and daughter Junu.
Sources at the Al Ahli Hospital said the man marched straight into the urology clinic and knifed the 58-year-old doctor before forcing him on his knees and slitting his throat.
Doctors and hospital employees rushed to the clinic but by then it was too late.
“He stormed into the clinic although nurses tried to prevent him… He then attacked the doctor and (killed) him like a sheep…
"The man then waited at the hospital until the police came and arrested him,” a source was quoted as saying.
“The man appeared furious… He blamed the Indian doctor for his relative’s death and attacked him without giving him a chance to defend himself… It was a heinous crime.”
