British police raid suspected chemical weapons laboratory in London

Needless to say, such intelligence, such potential threats, must be taken seriously. But where is the evidence here? One hopes MI5, which had been monitoring certain Bangladeshi youth for some time, knew what it was doing.

The BBC has more here.
