TWO terrorist suspects were arrested in West Yorkshire today.
The men have been arrested under the Terrorism Act in early morning raids in Halifax in an operation organised by Scotland Yard.
The pair, aged 25 and 29, were held in Halifax "on suspicion of the commission, preparation or instigation of acts of terrorism", police said.
Anti-terrorism officers from the Metropolitan Police, supported by colleagues from the West Yorkshire force, made the arrests at around 6am.
Four properties in the Pellon and Saville Park areas of Halifax as well as a flat in north London were being searched as part of the investigation, Scotland Yard said.
A Metropolitan Police spokeswoman said the arrests were part of an "intelligence-led operation".
The two men are currently in custody and were due to be taken to a police station in central London later today.
The spokeswoman added: "The men were arrested at separate houses in Halifax.
"Both premises, plus two others in the area, are being searched.
"As part of the same operation, officers from the Met's Counter Terrorism Command began searching a flat in north London. This search continues."
A Scotland Yard spokeswoman said today's operation was not armed.
She declined to specify where in north London the search was taking place.
A West Yorkshire Police spokesman said officers would regularly meet with people within the local community to keep them informed regarding the inquiry.
High-visibility police will continue to patrol the area to offer support in each of the areas affected.
Police have set up a hotline for information. Telephone 01422 337559.
