A post-mortem examination into the death of a migrant worker killed in a horrific coach crash in Staffordshire has proved inconclusive.
Piotr Wolski, 26, died after the coach he was in plunged down a steep embankment in driving rain in the village of Alton, landing in a garden 15ft below the road.
Mr Wolski, who was confirmed dead at the scene, was living and working at Lutton Farm, near Peterborough, at the time of his death.
Further tests will now be carried out following the Home Office examination, a Staffordshire Police spokesman said. Five people remain in hospital after one of the injured, a woman, was discharged from the University Hospital of North Staffordshire on Thursday.
Of the four people still at the hospital, the 62-year-old coach driver from Lincolnshire remains in a critical condition.
A 21-year-old Lithuanian woman at Birmingham's Selly Oak Hospital also remains critical.
Examination of the coach is likely to last several days.
Meanwhile, detectives have interviewed several witnesses from Alton and continue to interview passengers from the coach.
Any people who have yet to come forward - including those who helped in the aftermath of the crash - should contact police on 01785 234995 or Crimestoppers anonymously on 0800 555 111.
