An investigation has begun after a defendant doused himself with acid as he was being sentenced in court on Monday 1st May.
Marc Marshall, 54, was in the dock of Inner London Crown Court after being jailed for fraud when he poured a noxious substance onto his face.
He was taken to hospital in critical condition and a female custody officer who was guarding him in the dock was also treated.
The case is likely to raise searching questions about security in court buildings and how the liquid, which has not yet been identified, was apparently taken into the dock.
Marshall had been carrying a metal water bottle - although CCTV footage is believed to have shown that he had sipped from it as he passed through security.
