A tribute to Fusilier Lee Rigby has been damaged just days before the fourth anniversary of his murder.
Vandals ripped out flags from the memorial which stands outside Woolwich Barracks in Charlton, where he was killed by two Islamic extremists.
Scotland Yard said local officers are now carrying out “reassurance patrols” and that they are looking into reports that flags “had been damaged, with some possibly stolen”.
The attack is the second on the site since Christmas after a flag was taken in January.
People have voiced their disgust on twitter.
Fusilier Rigby, a drummer and machine-gunner with the 2nd Battalion Royal Regiment of Fusiliers, was killed outside his barracks while off duty on May 22, 2013.
The pair of killers knocked him down with a car before hacking him to death with a meat cleaver and knives.
Michael Adebolajo, who was given a whole-life term, and Michael Adebowale, who was jailed for a minimum of 45 years for his murder, were two Islamic extremists.
