Belgium could become the first country to introduce self-destructing briefcases to combat attacks on security vans.

Interior Minister Patrick Dewael said his staff were conducting talks with security and technology firms to develop cases that self-detonate when in the wrong hands.

Dewael added that signs on security vans warning that the cases within would automatically destroy their contents if removed would deter armed robbers.

A spokeswoman for secure transport company Brink's, Maxime Vanden Daele, said: "We are hoping Belgium will become the first country to make the use of such cases compulsory."
