Police continue to question letter bomb suspect

Police have been granted an extra day to question a school caretaker in connection with the recent series of letter bomb attacks at businesses in Britain.

Miles Cooper, understood to be in his twenties, was arrested at his home in Cherry Hinton near Cambridge on Monday. He is being held at an undisclosed police station.

Mr Cooper works as a caretaker at Teversham Church of England Primary School and a search is continuing there, although this is expected to be completed today.

Specialist forensic teams are expected to spend several days searching his home.

Nine people have been injured by seven letter bombs, which have been sent to a number of business addresses in the UK since mid-January.

Police believe that all the devices are linked. The bombs are understood to have been homemade pyrotechnic-style devices contained in A5 jiffy bags. At least two of the devices contained glass.

Police have warned that other packages containing explosives could still be in the postal system.

Among the addresses targeted were three forensic science laboratories, Capita in London, which runs the capital's congestion charge, and the DVLA in Swansea.
