The Privacy Commissioner will ask police to provide details of how copies of confidential statements were dumped in a housing estate's refuse depot. The Office of the Privacy Commissioner for Personal Data said it would check whether the force had complied with the law, after the material was found at Wu King Estate, Tuen Mun, on Monday. The police have apologised and said the statements were mistakenly dumped by an officer's mother who was tidying up in preparation for moving house. The Personal Data (Privacy) Ordinance says all possible steps should be taken to ensure personal data is protected against unauthorised or accidental access, processing, erasure or other use. A spokesman for the Privacy Commissioner said: 'We'll write to the police to ask for information about the case. 'We'll try to find out if the police have complied with the law on security of personal data by adopting sufficient measures.' Tuen Mun District Commander Chief Superintendent Ian Seabourne said he had spoken to the officer's mother. 'She was crying. She was just doing some cleaning work but put her son into such an embarrassing situation,' he said.
