Bomb disposal experts have carried out seven controlled explosions at a Derbyshire home where a highly dangerous substance was found, ITV News Central can reveal.
Police say the substance they have been dealing with is so volatile that at least one of the explosions was carried out a mile away from the scene.
Officers were even concerned about transporting the material by road, and considered evacuating homes along the entire route it was being taken.
The army bomb disposal team are now back at the scene ensuring all traces of the substance have been removed.
