A nurse stopped to help at the scene of a fatal crash after a long hospital shift.
Police officers say they would like to speak to the currently unidentified nurse, who is believed to have been travelling along the M4 on her way home after finishing a 13-hour shift at Morriston Hospital in Swansea when she came across the collision and stopped to assist with CPR.
The victim of the crash, which happened on the M4 westbound between junctions 46 and 47, shortly before 8.35pm on February 18, has since been named as 41-year-old Thavarajah Sasikaran from the Waun Wen area of Swansea.
