The mother of Josh Hanson, who was stabbed to death in a bar in Hillingdon in 2015, has spent the eve of his third anniversary, urging Londoners to help find the man suspected of carrying out the killing.
Tracey Hanson spent time at Victoria, handing out fliers with information about Shane O'Brien. The 29 year old is wanted over the murder - and is believed to be in Europe.
