Scotland Yard said the man they want to speak to has since “significantly altered his appearance” from the CCTV footage.<\/p>\n
People have been urged not to approach him.<\/p>\n
A 23-year-old man was arrested on Monday on suspicion of conspiracy to commit murder and remains in police custody.<\/p>\n
Ch Insp Allam Bhangoo said: “We remain committed to securing justice for Erdem as our thoughts remain with his loved ones at this unimaginably hard time.<\/p>\n
“While I am pleased my team have made an arrest, our work continues at pace to investigate the full circumstances around Erdem’s murder.<\/p>\n
“We are now releasing the details and images of a man we urgently need to speak to in connection with the incident.<\/p>\n
“We are carrying out a number of inquiries to trace him but are also asking for the public’s help.<\/p>\n
“If you recognise him or have any information on his whereabouts please come forward.<\/p>\n
“We are still appealing for anyone with wider information about the shooting, including any CCTV, doorbell, dashcam or mobile phone footage, to also contact us.”<\/p>\n
