London lost and found items
If you've lost any possessions it can be frustrating. Always check with Transport for London (TfL) lost property and your local police station first. If no luck, social media is a great tool, especially Twitter.
Give @TaxiFound a tweet to put out a message to a large network of taxi drivers who'll do their best to locate your lost items. You'll find the current items lost and found in taxis here on this page.
