Terror suspects held over deadly poison find

Six terror suspects are being questioned by detectives after traces of the deadly poison ricin were discovered.

The six men of north African origin were arrested after an operation by the anti-terrorist branch in north and east London.

The yard said 'equipment and materials' were found at an address in Wood Green where one of the man was also arrested.

A woman who was also arrested has been released.

Ricin was the poison used to murder Bulgarian exile Georgi Markov in a political assassination in London in 1978.

The news comes weeks after security sources warned of a possible terror attack involving London underground.

In a joint statement issued this afternoon, anti-terror chief David Veness and Deputy Chief Medical Officer Dr Pat Troop said: "In the early hours of Sunday, 5 January, 2003, six men and one woman, were arrested under the Terrorism Act 2000 at premises in north and east London by officers from the Metropolitan Police anti -terrorist branch.

"This successful joint operation between the anti-terrorist branch, MPS Special Branch and the Security Service follows receipt of intelligence.

"A quantity of material and items of equipment were found at a residential premises in Wood Green, north London, where one of the men was arrested.

"This material has been analysed at the Defence Science and Technology Laboratories at Porton Down. A small amount of the material recovered from the Wood Green premises has tested positive for the presence of ricin poison."

Wood Green - I go past there on the way to and from work. It's only a matter of time.
