"Post box damaged in 'explosion'
Police and Royal Mail officials are investigating after an explosive device damaged a post box in Northumberland.
Northumbria Police said officers were alerted when a member of the public reported an "explosion" inside the box in Haltwhistle on Friday morning.
A spokeswoman said officers found the front metal plate had been blown off by the blast.
She said no-one was hurt in the incident and that a "device" had been recovered from the scene."
Not sure about all those 'apostrophes'!
