The son of a Premier League footballer has been expelled by his school after allegedly attacking 15 fellow pupils with a diabetes needle.

The 14-year-old, who cannot be named for legal reasons, took the needle and jabbed his classmates "as a prank" at the "exclusive" school in South-East England, according to The Sun.

All of the pupils affected by the incident were forced to take tests for HIV and hepatitis, although all came back negative.

"It's been dreadful," said a source. "The whole school is very upset about it. It's a fantastic school, second to none. It's a sensitive situation."

The newspaper describes the boy's father as having "played abroad but made his reputation in the Premier League with a superb goal-scoring record. He is a favourite with his club's fans, boasts a trophy cupboard crammed with honours and has made appearances at international level."

Another 14-year-old was also expelled for his part in the incident.
