A university student hit by a train has had part of her leg amputated and suffered a crushed skull after she lost her footing.
Ava Harlow, 20, from Amesbury in Massachusetts, US, became trapped underneath a moving train at the BU Central Station in Boston on January 27.
The Massachusetts Bay Transportation Authority police were called to the scene at around 11.30pm after the student got off at her stop with her friends but realised some of them were still onboard.
