The men – who were apparently assessed by MI5 as not posing a threat requiring “immediate intervention” – were arrested following the hacking to death of a serving soldier in the street in Woolwich, southeast London.
Sky’s crime correspondent Martin Brunt said one suspect had been identified as Michael Adeboloja, a 28-year-old Londoner of Nigerian descent.
Police investigating the attack have been searching an address in Greenwich and another in Lincolnshire, believed to be connected to Adeboloja.
Brunt added: “We believe it is his father’s house that is being searched by Lincolnshire Police on behalf of counter-terrorism command at Scotland Yard.”
Relatives of the dead soldier are believed to have been informed and his identity is expected to be released later today. A post mortem is being carried out on the body.
