Detectives are appealing for information in connection to the murder of a man in east London last April.

Alfred Liverpool, 25, was shot in Rushcroft Road, Brixton, and died at the scene.

The Detective Chief Inspector leading the investigation, Adnan Qureshi said: "A year has passed since Alfred was fatally shot, and despite extensive enquiries we are still unable to provide his family and friends with the answers they desperately seek.

"I have no doubt there are people who know what happened, and I ask them to find the courage to come forward - to place themselves in the position of a parent who has lost a son, or a friend who has lost someone they cared for, and to imagine the devastating effect such a loss could have, coupled with the anguish of knowing those responsible are still at large."

DCI Qureshi added: "All information is treated confidentially and at court there are a wide number of measures that can be used to help protect witnesses, including voice distortion techniques, giving evidence from behind a screen or using a false name.

"The measures are granted by the courts and are tried and tested. There have been a large number of cases across the country where these measures have worked and have helped families get justice."

Police in particular want to speak to members of the Polish community as well as members of the media who serve London's Polish community and media outlets in Poland.

Reports last year say the suspects were in their early 20s and left the scene in a small red car.

A reward of £20,000 is being offered for information leading to the arrests of person(s) responsible.

Anyone with information is asked to call the incident room on 020 8247 4554.
