Arab Malaysian Banking Group founder Hussain Ahmad Najadi was gunned down in cold blood, while his wife was seriously injured when they emerged from the Kuan Yin Temple in Lorong Ceylon this afternoon.

A gunman who crept from behind, fired randomly at Hussain Ahmad, 75, and his 49-year-old wife at close range, killing the renowned banker on the spot near a car park.

The septuagenarian sustained two shots in the chest while his wife was hit in the left hand and right leg in the 2pm incident.

Initial police investigations revealed that the gunman was among three people who waited outside the temple for Hussain Ahmad who was in a private discussion with a colleague involving a share transaction.

The gunman, who wore sports attire, dark glasses and a cap, was believed to have escaped in a taxi, together with his accomplices.

Kuala Lumpur CID deputy chief ACP Khairi Ahrasa said, while the motive of the killing had yet to be estabilished, the police believed it could be business-related.
