The BBC are reporting that
A man has been shot by police during a raid involving 250 officers carried out under the Terrorism Act.
He was taken to a nearby hospital after police searched a house in Forest Gate, east London. His injuries are not life-threatening.
A 23-year-old man has been arrested and is currently in custody at a central London police station.
SkyNews is claiming that
Police sources have told Sky's Crime correspondent Martin Brunt detectives expect to find chemical or biological agents in the house in Lansdown Road, Forest Gate, east London.
They were allegedly being primed for a suspected bomb plot against the UK.
He said: "These brothers were being watched for many weeks if not months.
"Police are not expecting to find conventional weapons. They are looking to find chemical ingredients of some kind."
We'll see. You'd like to think that 250 police officers don't jump out of bed for an early morning raid over nothing.
