THE prison ombudsman today began his independent inquiry into the death of Dr Harold Shipman at the prison where he died.

Prison And Probation Ombudsman Stephen Shaw arrived at Wakefield Prison at 10am to talk to staff and prisoners about the apparent suicide of the former GP.

Britain's most prolific serial killer was discovered hanged in his cell yesterday morning with a ligature made from bed sheets.

As he entered the prison, Mr Shaw told reporters:

"The investigation is now starting and I have made very clear that I intend a very full and entire investigation.

"There has been a lot of speculation about Dr Shipman's death.

"It is now time for me to uncover the facts."
