A house in a Lincolnshire village has been raided by Met police officers investigating yesterday's alleged terror attack in Woolwich.
Officers swooped on the detached house as the name of one of the suspects was revealed on internet forums and Twitter as Michael Adebolajo.
He has been identified as the alleged killer seen ranting on video shortly after the murder of the soldier in Woolwich.
It is understood the men, who are being treated in separate hospitals while under arrest, are most likely to be British citizens of Nigerian descent who have converted to a radical form of Islam.
However, they are not thought to have links to terror groups based in Nigeria, such as the jihadist militant organisation Boko Haram.
Police were today seen outside a £365,000 detached house in a Lincolnshire village where they raided a home where Adebolajo is listed as having lived in the past.
There was no answer at the address believed to be that of Adebolajo's father, named by neighbours as Anthony Adebolajo.
Mr Adebolajo, 56, is believed to be a trained nurse now working in a managerial capacity within the NHS.
The modern property was being monitored by two police patrol cars stationed outside.
Later in the morning, plain clothes officers, thought to be from the Metropolitan Police, arrived at the modern estate and the house and driveway was sealed off with police tape. An officer at the scene described the property as a 'crime scene'.
Mr Adebolajo bought the property in 2002. At one time a woman who wore a burka was thought to live with him.
They believed he had up to four grown up children, although few if any are thought to have stayed at the house for any period of time.
Michael Adebolajo was listed as being a resident there in 2004, shortly after the family moved in.
One nearby resident said: 'I know his family have ties to London, but whoever is at this house is very secretive.
'The curtains are always drawn at the front and the back, I've never seen anybody in the garden, either.'
Neighbours said the house has been home to the same family for about a decade and the blinds at the house were today closed.
