Pupil's dirty trick

A British pupil was expelled from school after placing his genitalia in a teacher's drinking mug.

photographic evidence of the bizarre prank was posted on the internet and the unsuspecting teacher ended up taking time off work with stress.

A source said: "The photo was of the lad dangling his private parts inside the cup belonging to the teacher. She later drank her tea from it."

An investigation showed that the unnamed boy had been urged to carry out the trick by friends via social networking website Facebook.

Three other pupils were suspended from Benfield School in Newcastle.
