Detectives investigating the racist murder of Stephen Lawrence have said that all “identified lines of inquiry have been completed” and it has moved to an “inactive phase”.
The 18-year-old was killed in an unprovoked attack in Eltham, south-east London, in April 1993.
Gary Dobson and David Norris were convicted of his murder in 2012.
Met Commissioner Cressida Dick said Mr Lawrence’s family had been told about the latest operational developments.
Duwayne Brooks, who was with Mr Lawrence on the night he was murdered, has also been told about the Met’s decision, the force said.
‘We will continue’
Ms Dick said she was sad that the Met had been “unable to secure any further convictions for Stephen, his family and friends”.
She added: “The investigation has now moved to an ‘inactive’ phase, but I have given Stephen’s family the assurance that we will continue to deal with any new information that comes to light.
The latest phase of the investigation into Stephen’s murder began in January 2014, with Det Ch Insp Chris Le Pere taking over as the lead officer.
Since then more than 240 new witness statements have been taken.
