Conflicting reports on Boston arrests by police

Law enforcement officials are denying that arrests were made at the Westin Hotel in Boston.

Heavily armed police and FBI officers entered the building with fibre-optic equipment, which was used to look under hotel room doors.

They say the 16th floor room they searched was empty, but a number of items were found, believed to be linked to the planning of the atrocities.

Meanwhile, those taken into custody in Florida are believed to have been aviation students linked to Osama Bin Laden, one of whom had stayed at the house of an American couple.

Earlier, police discovered flight training manual and other items in a car at Logan airport in Boston.
