A teenager saved a woman's life on the way home from college.

Tiyana Lartey was on the bus near Queensbury Morrisons when she saw a 93-year-old woman fall and violently hit her head on the ground.

The 18-year-old, who goes to Stanmore College and was on her way home to Cricklewood at the time, noticed people were just taking photos and laughing on the side.

She quickly jumped off the bus and ran to the aid of the woman, who was bleeding profusely.

The bus driver also stopped and called an ambulance while Tiyana comforted the woman, trying to calm her bleeding.

Tiayna, who is trained as a cadet, had to give a statement to police officers - who then dropped her home.
