The distraught mother of a teenager who was stabbed to death has appealed for witnesses to come forward as the 10th anniversary of her son’s death approaches and police offer a £20,000 reward for information.

18-year-old Warren Graham was stabbed three times – twice in the chest – while out with friends at the Pavilion Nightclub in Lower Clapton Road on October 26, 2004.

Warren was attacked after an on-stage row erupted that police believe was between one of his friends, performing as an MC, and another group of youths over control of the microphone.

Warren was taken to Homerton Hospital but died shortly afterwards.

His mother, Cheryl Evans, said Warren was a happy-go-lucky, family-orientated young man who was looking forward to living his life.

She said: “Warren had an amazing smile. He was nicknamed the Pied Piper because younger kids were always drawn to him and he was just about to start living his life. The week that he got killed he was so excited about a job interview he was going to.

“There has been no closure. He was my only child and now there are no grandchildren, no wedding, no graduation from university – all of that has been taken away from me and my family while this person who killed him is living his life.

“I should be celebrating all of his birthdays, but now I have to go to the cemetery with a balloon and talk to a gravestone. That’s what I’m left with.”

Ms Evans added that witnesses who have grown up with their own children now might understand how she feels.

She said: “Please don’t be afraid; the police have protection methods. I’m begging people out there – we can’t bring him back, but he deserves justice because he didn’t do anything. Please give us some solace and some peace.”
