Following Majek’s conviction Carla Harris, from the Crown Prosecution Service, said: “Rhiannon Whyte should have been able to go to work and come home safely – but Deng Chol Majek robbed her of her life and future.
“He attacked her for no reason, and callously left her bleeding on a station platform.
“He then appeared to rejoice in his actions, having been caught laughing and dancing on footage an hour later.”
Det Ch Insp Paul Attwell, of British Transport Police, said it was very unlikely the motive behind Majek’s decision to “launch his savage attack” will ever be known.
He said the killer appeared “completely unbothered, bored even” throughout the trial, much to the distress of Ms Whyte’s family.
“It was a brutal, cowardly and unprovoked attack on a vibrant and selfless young woman, who had her whole life ahead of her,” Det Ch Insp Atwell said.
