In an unusual admission of error, the ruling Communist Party’s top disciplinary body has now revoked its earlier decision – and sent a “solemn apology” to Dr Li’s family.

Two police officers have been issued with “disciplinary punishments” for their role in the original incident, a report by the National Supervisory Commission said.

Investigators found that Dr Li hadn’t disrupted public order with his actions – describing him as a professional who had fought bravely and made sacrifices.
