Eight schoolboys arrested over a racist chant made at a teacher's leaving party and posted on the internet have been bailed for a third time until 10 May. A ninth boy, arrested last weekend, has also been bailed while Hertfordshire police continue their inquiries.
The nine boys, aged between 15 and 16, are pupils at a school in Ware and were arrested after an allegation of anti-Semitism was made.
A police spokeswoman said: "We take allegations of racism very seriously."
The boys were questioned about the film posted on the internet in March and were bailed twice after separate interviews.
A full police investigation into the allegations continues.
The spokeswoman said: "When the youths answer their bail the appropriate action will be taken. As this is an ongoing investigation it would be inappropriate to comment any further at this stage."
