The police have arrested a surgeon who is accused of stealing a kidney from a patient during an operation to remove his gall bladder. The stolen kidney was recovered from a laboratory in Nazimabad, where it was reportedly sent for some diagnostic tests. The Tamuria investigation police said Saturday that Dr Mateen was arrested from Rashid Minhas Road near Millennium Mall, where he came to see his brother late Friday night. The police said that they were keeping an eye on his brother, who is a builder by profession. According to the police, Dr Mateen had said in his initial statement that he had mistakenly taken out Kashif's kidney. He said that he didn't do it intentionally and concealed the fact from the patient because he feared retaliation. The doctor, 38, had said that he had performed almost 1,000 surgeries during his five-year professional career as a surgeon. Investigation Officer Sub Inspector Aijaz told Daily Times that they had found evidence that some other doctors and administrator of Medi Complex were also involved in the incident. He said that they are absconding and the police are searching for them. Aijaz said that the kidney stolen from Kashif had expired and could not be transplanted to him or anyone else.
