Man Tied In Sack And Dumped In River

Troubled Tyneside man Terence Crozier tried to escape from court, where he was being tried for a crime of wounding, which was
unconnected to the Sibbet murder.
When caught he told police he was scared for his safety if he was convicted and had to go to prison after an incident, where he had been tied up in a sack and thrown in the river.
Crozier stated that this was because he ‘knew too much’ about the Sibbet murder.
He was eventually convicted of the crime he was standing trial for but instead of a custodial sentence in prison he was sent to
Broadmoor Hospital for the Criminally Insane, where he remained for the rest of his life.

When consulting the National Archives for more information on the case it was discovered that part of Crozier’s court file had an order placed upon it, removing it from public view for 73 years.
What is contained in that file that the public can’t see and does it concern the murder of Angus Sibbet?
