Ross Jelf, of West Bromwich, suffered a fractured skull. His friend Richard Comery, 14, from Birmingham was hit on the leg as they travelled on the motorway between Liege and Brussels on Saturday. Richard shrugged off his injury yesterday to take part in a Duke of Edinburgh walk. The two boys were among a party from Dartmouth High School.
Richard's father, Tony Comery, 46, said yesterday: "Some yobbos lobbed a concrete brick and it went through the skylight of the coach. It bounced off his leg. Richard's back home now, but he is very concerned about Ross."
