A businessman, who lost his two teenage daughters in the Hillsborough football stadium disaster, has hit out at a sick hacker who used a Government computer to insert insulting references to the tragedy on Wikipedia.

The Cabinet Office is making urgent inquiries into the claims.

Keighley businessman Trevor Hicks (left), a former chairman of the Hillsborough Family Support Group, described it as “appalling, offensive and inappropriate,” and called for the culprit to be exposed and disciplined.

Mr Hicks, whose daughters, Sarah, 19, and Victoria, 15, died together at Hillsborough, said: “The timing is appalling, when we have all given our family statements to the inquest, which was extremely difficult for us to do.”

Mr Hicks recently gave evidence about his daughters to the new Hillsborough inquest.
