had modified by hand to fit the gun. Bentley carried a knuckle-duster, which he had been given by Craig, who had been fined the previous year for possessing a firearm without a certificate. At around 9:15pm, neighbours called police after spotting Craig and Bentley climbing over the gate and up a drainpipe to the roof of the warehouse. When police arrived, Craig and Bentley hid behind the lift-housing. Craig taunted the police. One of the officers, Detective Sergeant Frederick Fairfax, climbed the drainpipe to the roof and grabbed hold of Bentley, but Bentley broke free. What happened then is uncertain: police witnesses later claimed that Fairfax ordered Craig to "Hand over the gun, lad" and Bentley shouted, "Let him have it, Chris". Craig fired, striking Fairfax in the shoulder. Fairfax was nonetheless again able to restrain Bentley, who told Fairfax that Craig had further ammunition for the gun.

The first to reach the roof was Police Constable Sidney Miles, who was immediately killed by a shot to the head. After exhausting his ammunition and being cornered, Craig jumped 30 feet (10 metres) from the roof onto a greenhouse, fracturing his spine and left wrist, and had to remain in hospital.

They were tried by jury before the Lord Chief Justice, Lord Goddard, at the Old Bailey in London between 9 December and 11 December 1952. Christmas Humphreys, Senior Treasury Counsel, led for the prosecution. At the time of the burglary attempt and Miles's death, murder was a capital offence in England and Wales. Minors under 18 were not sentenced to death: consequently, of the two defendants, despite Craig having fired the fatal shot, only Bentley faced the death penalty if convicted.

Bentley's best defence was that he was effectively under arrest when Miles was killed. There were three principal points of contention at trial: Firstly, the defence claimed there was ambiguity in the evidence as to how many shots were fired and by whom. A
