Details are still coming in on the incident in Uxbridge this lunchtime (Tuesday, November 11) that led to police locking down much of the town centre.
Officers were called at 12.14pm to High Street, Uxbridge. Shoppers and staff at shops along the High Street were told to leave the area by police and many people gathered outside the civic centre. A number of bus routes were diverted.
Hillingdon Police have confirmed a man was arrested and details are expected soon .
The incident, two days after a Remembrance Sunday that passed off peacefully, was however less than a week after a man was arrested in Uxbridge , one of four held by Met Police overnight on Thursday, November 6, in West London.
A house in Hayes was searched, and there was speculation that the raids, in Hounslow, Southall and High Wycombe as well as Uxbridge, were to head off of a possible plot to target Remembrance ceremonies.
The men are still in custody and enquiries continue.
There is no suggestion that the incident in Uxbridge today had anything to do with Islamic terrorism but police and security services are on high alert and sensitive to any possible threat.
UPDATE: A 40-year-old man was arrested by police on suspicion of making a threat to cause an explosion in the incident in Uxbridge on November 11.
He was taken to a West London police station where he is being detained.
