A Beijing brain specialist who has promised to help a paralysed police officer had been contacted through a third party by the force, Police Commissioner Dick Lee Ming-kwai said yesterday. Neurosurgeon Ling Feng would come to Hong Kong as soon as possible, he said. 'Dr Ling has already promised to come to Hong Kong, as far as I know,' Mr Lee said, adding that officials were doing all they could to speed up her arrival. Constable Jacky Chu Chun-kwok's family had said on Saturday that Dr Ling, of Xuanwu Hospital, had agreed to see the injured officer in Kwong Wah Hospital. But Dr Ling was not in a hurry to start treatment on the constable. 'I must first visit the patient in person to decide what kind of treatment is best for him. There is no hurry - this is not an urgent case anymore. He has been in that condition for nine months already. I will go to see him as soon as I can.' Dr Ling previously helped a Phoenix TV news anchor recover from horrific brain injuries sustained in a train accident. She treated Tanya Liu Hai-jui using hyperbaric oxygen therapy, a treatment that uses gas under high pressure. Mr Lee said they would provide as much information about Constable Chu as they could to medical experts from the mainland. 'We hope they can gain a better understanding about Constable Chu's condition so that they can take action to help him. We are hopeful that Constable Chu will recover,' he said. The policeman suffered serious brain injury as the result of an attack while he was patrolling in Cheung Sha Wan in July. He suffered a wound to the neck that severed an artery and starved his brain of oxygen. He has been in a near vegetative state because of brain damage caused by blood loss.
