A vandal has been caught on CCTV smashing a bottle over a Stephen Lawrence memorial plaque while walking alongside a woman with a pushchair.
Police released the footage in a bid to trace the man and woman after the tribute to the murdered teenager was covered in shards of broken glass yesterday.
Images released by Scotland Yard show a man in white shorts, white trainers and a blue sleeveless shirt accompanied by a blonde woman pushing a stroller with a child in it.
Detective Sergeant James Bray said: "Anyone with information concerning the incident or who recognises this man and woman are asked to come forward and assist us with their inquiries."
In previous years yobs have chipped and poured paint and flammable liquids on the pavement tribute at the spot where the black 18-year-old was killed in Eltham, south London.
There was no immediate reaction from either of Stephen's parents, who were at the Old Bailey last week for the pre-trial hearing of two men accused of his murder.
Gary Dobson, 36, and David Norris, 35, deny murdering Stephen in a racist attack in April 1993.
Dobson and Norris, both of south London, go on trial on November 14.
