Olmert brother knocks out reporter

The brother of former Israeli Prime Minister Ehud Olmert has knocked an Israeli sports reporter unconscious.

Basketball executive Irmi Olmert was apparently upset over some on-air comments by a reporter for Israel's Channel 5 sports network.

Mr Olmert confronted him after a game and ended up punching him in the face, briefly knocking him unconscious.

Sport 5 footage of the incident last night shows the two arguing, followed by a loud thump and then the reporter lying motionless on the basketball court.

The actual punch is not captured, but Mr Olmert is heard saying: "I'll show you for speaking to me that way. I punched him. Did you hear what he said about me?"

Israeli police have questioned Mr Olmert, while the reporter was hospitalised and later released.
