Four stabbing victims killed in London within 24 hours include two teenagers

Two teenagers are among four people to have been stabbed to death in a series of apparently unrelated attacks across London within a 24-hour period.

Scotland Yard confirmed the male victims - a 17-year-old, 18-year-old and a 20-year-old on New Year’s Eve, and a 20-year-old in the early hours of Monday - all died as a result of their injuries, while a fifth is critically ill in hospital.
