He said: "If you imagine what that explosion would have looked like without that [mitigation] it really would have been a catastrophe, a 250kg bomb. ...
The force said agencies had "assessed the damage caused by the explosion with a number of car windows broken, the top of the scaffolding on the bridge affected and some damage to the flood wall".
