ONE of the officers charged with overseeing the investigation into Glynn Harding's letter bomb campaign has voiced his concern about how easily the Crewe man obtained bomb making instructions off the internet.
Deputy Chief Constable Pete Walker of the Yorkshire Police Force said: "We are concerned that this sort of information has been in the public domain for some time."
Other concerns for the police include the fact that a lot of the components needed are readily available, and the information off the internet gave instructions on how to put them together.
Police sources also said that one method used to track the letter bomber down was the use of library checks to see if certain books had been booked out of libraries, which could help in the making of such devices.
