Bibaa Henry and Nicole Smallman were stabbed to death at Fryent Country Park in June last year
A teenager has been found guilty of murdering two sisters in a London park last year in what was described as a “frenzied and relentless” attack.
Danyal Hussein, 19, was convicted by a jury at the Old Bailey after more than four weeks of hearings in which DNA, CCTV and other evidence connected him to the murders of Bibaa Henry and Nicole Smallman.
