AQ Khan 'nuclear middleman' freed
The Malaysian government says it has released an alleged middleman in the nuclear secrets ring run by disgraced Pakistani scientist AQ Khan.
Buhary Syed Abu Tahir, a Sri Lankan businessman, was arrested in Kuala Lumpur in May 2004.
US President George W Bush described him as AQ Khan's "chief financial officer and money launderer".
Malaysia's home minister said that Mr Tahir was no longer a threat to national security.
