Under Section 34, the Authority's obligation to provide for safe custody and restoration of property found on its premises (not in proper custody) applies:

Section 34 casts a duty on the Authority to secure the safe custody and restoration of lost property found on its premises or under its overall control (including property found in aircraft on such premises), but this duty operates 'subject to such regulations as the Authority may make in this behalf' - meaning the precise mechanics (custody procedures, restoration conditions, minimum value thresholds if any, disposal timelines) are left to be worked out through the Authority's own regulations under Section 42(2)(f) and (g), rather than being unconditionally or exhaustively codified in the Act itself. There is no statutory minimum-value threshold or police-complaint precondition written into Section 34 itself.
