Two students who stopped a violent sex attack on a young woman have described chasing the rapist away.
Romanian national Marius Glad Trimbitas, 33, was jailed for eight years for rape, assault by penetration and making threats to kill.
Kayne Fair and Adam Bouabida told Alice Bhandhukravi about the part they played in bringing him to justice.
Det Insp Jackie Wakeford-Smith said she believed Trimbitas could have attacked others.
