The sentencing exercise over the deaths of four men from Suffolk who were crushed to death six years ago will last around two days and is expected to be heard in London.

Daniel Hazelton, 30, his brother Thomas Hazelton, 26, Adam Taylor, 28, and Peter Johnson, 42, died in Great Yarmouth on January 21, 2011 when a large steel cage they were working in collapsed in the Claxton Engineering Services' Yard.

The Health and Safety Executive (HSE) brought charges against three companies and one director.

Two of those companies were due to go on trial at Norwich Crown Court and a jury was sworn in but before the trial got underway Claxton Engineering Services offered a plea.

Encompass Project Management Ltd, of Old Market Street, Thetford, has also pleaded guilty to a Health and Safety charge and its director David Groucott, pleaded guilty to a charge under section 37.

Mr Justice Baker today set sentencing for May 23 and 24 in London at a court to be decided.
