A 28-YEAR-OLD woman who died on a train may have died from 'leaning out a window', police have said.

The woman, from Penarth, received serious head injuries while travelling on a train between Bath and Keynsham on Saturday December 1 at 10.10pm.

A statement from the British Transport Police confirmed she died at the scene.

The statement said: "Officers from British Transport Police attended along with colleagues from Avon and Somerset Police and South Western Ambulance Service but despite their best efforts, the woman died at the scene.
