Armed police have flooded London’s streets as the terror threat level was raised to critical amid fears the Parsons Green bomber could strike again.
The introduction of Operation Temperer will see soldiers replacing police at key sites including nuclear power plants to free up extra armed officers for regular patrols.
Scotland Yard said last night it is making ‘excellent’ progress in hunting the suspected terrorist who set off a crude bucket bomb on a packed commuter train by Parsons Green tube station in west London on Friday.
Had it worked as intended, a massive blast of fire would have killed dozens on the new, open-plan style train which — at 8.20am yesterday — was close to its capacity of nearly 1,000 people.
Mrs May said in a statement from Number 10: ‘The Joint Terrorism Analysis Centre has now decided to raise the threat level from severe to critical — this means their assessment is that a further attack may be imminent.’
