Police are hunting five suspects involved in the murder of a 14-year-old boy who was rammed off his moped and stabbed.
Jaden Moodie died on January 8 after the attack in Bickley Road, Leyton, east London.
Five men in a black B Class Mercedes smashed into his moped before three of them got out and stabbed him more than seven times.
Speaking at the scene of Jaden's death on Tuesday, Detective Chief Inspector Chris Soole said the community is "up in arms" about the "particularly barbaric" death.
Officers are returning to the scene of the crime on Tuesday evening, one week since Jaden's death, to appeal for witnesses. They will also visit Carlisle Road, where the Mercedes was dumped.
Investigators are appealing for anyone with information to come forward. They can contact police on 020 8345 3734, or Crimestoppers anonymously on 0800 555 111 or at www.fearless.org.
