A man stabbed to death in a shopping centre in east London is the 38th person to be murdered in the capital this year - with eight people killed in the last seven days.
The 21-year-old victim was attacked at around 9.30pm on Tuesday night.
At the Stratford Centre on Tuesday paramedics battled to save his life after he collapsed with knife wounds.
Last month Commissioner Cressida Dick spoke out about knife crime and a "senseless waste of life" after two teens were murdered in Camden, north London.
Since the start of the year eight teenagers have been killed. Last year 116 murder investigations were launched by Scotland Yard.
