More information flows into Operation Patch

Auckland City Police investigating the disappearance of Anan Liu, the 27 year-old mother of abandoned three year-old Qian Xun Xue, have had a report of an unconfirmed sighting of Anan in the Auckland suburb of Balmoral on Tuesday, September 11.

The reported sighting was notified to Police via the Operation Patch 0800 number - 0800 272 824. Officers will follow up on the information provided today to determine its authenticity.

Detective Senior Sergeant Simon Scott says the information flow to the Operation Patch 0800 number has been encouraging and included a call from a woman who says she is the "missing" older daughter of Nai Yin Xue.

"She is being very co-operative and is safe and well and lives in New Zealand. We don't have any concerns for her safety and will respect her wishes that she not be subjected to any publicity," Mr Scott said.

"We will speak to her again today as part of our profiling inquiries around Mr Xue.

"As each hour goes by our concerns for Anan grow accordingly. There's been no activity on her bank accounts since last Monday - September 10 - and the mobile number we have for her goes directly to voicemail."

Police today will examine the two family cars that have been seized under warrant, as well as the Keystone Ave family home address in Mt Roskill.
