Found an iPad in Marylebone

It looks quite new and well looked after. Has a pic on it of an animal. I wanted to pick up a tote bag on a pavement and there it was. I took it to Apple Store there said they could help and couldn’t take it. I tried to call 101, but it’s soo long to wait them pick up.

Is there more effective way to find the owner than dropping it at a police station? ( didn’t realise that there’s nearly no police station in this city).
