Environment groups offer €30k reward to identify wolf's killer

Naya, the first wolf sighted in Belgium for a century, believed to have been killed by hunters

Environmental groups are offering a a30,000 (27,000) reward for information that helps identify who killed Naya, the first wolf sighted in Belgium for a century when she entered the country last year.

The wolf's arrival completed the return of the predator to every mainland country in Europe, turning back decades of persecution.
