April 2000 or Shortly After: British Authorities Concerned A. Q. Khan Network Poses Threat to Customs Agent

British authorities continue to be concerned that the A. Q. Khan nuclear proliferation network may take action against a British customs agent named Atif Amin, who had headed an investigation into the network. Members of the network had previously discussed taking action against Amin when he was in Dubai (see Late March 2000), and this had led to his investigation being curtailed (see Late March 2000). Discussions between network members are overheard by the British intelligence agency MI6, which passes the information on to British Customs. Customs talks to Amin about improving security around his home and investigates network members based in Britain who may pose a threat to him. However, the risk appears to be minimal while he remains in Britain. On the other hand, Khan associates attempt to locate members of his extended family still living in Pakistan, and Khan apparently vows to take action against Amin if he ever comes to Pakistan.
