Missed this one over the weekend:
Police chiefs have launched a major investigation after the theft of a computer database containing thousands of top-secret mobile phone records from terrorism and organised crime investigations.
…Forensic Telecommunications Services, whose clients include Scotland Yard, The Police Service of Northern Ireland, HM Revenue and Customs and the Crown Prosecution Service, specialises in tapping mobile phone calls made by criminal suspects. The stolen security-protected server contained the minutiae of phone calls it had screened, including the identity of the person who had made the call, as well as the exact time and location of the suspect when the call was made.
