From the BBC web site:

Man sought over TV bottom pinch

A man who pinched the bottom of a Channel 4 News presenter during a live broadcast is being hunted by police.

Sue Turton was speaking to the camera from Oxford's flood-hit Osney Island when the man was seen on film walking past her.

Ms Turton continued her report despite the distraction. She said she did not want to pursue the matter.
