A new information sharing arrangement between the police and the MTR Corporation will make it easier to reunite people with items they have lost on the rail network, the force said on Thursday.

People can now report lost property at a self-service kiosk in Admiralty MTR Station. It's the first such kiosk to be installed anywhere other than police station report rooms or reporting centres.

"After you make a report through our self-service kiosk, the informant needs to give consent before we pass the data to the MTR's system... And also, the data is encrypted before the transmission, so it is a very secure system," said superintendent Tony Lam.

"Through the new arrangement, at the same time [the informant] can make a report to two different systems. No matter if the lost property is eventually found on the ground or within the railway system, the [chance] of recovering the items [is higher]."

The force said it is considering installing the self-service kiosks at more locations, including Tai Wai and East Tsim Sha Tsui MTR stations.

Other than lost property, people can also use the kiosks to report non-emergency cases such as deception offences and traffic complaints.
