send them a message, and post it here so we can read it, mine was:My daughter has lost her treasured bear 'Boz' on Tuesday 26th August at around lunch-time. We think he fell down under a bench by the side of the Thames between Tower Bridge and London Bridge whilst we were having lunch.
We had just walked down from Monument to the river.
We came back 30 minutes later once we realised he was missing but he was nowhere to be seen.
He has no commercial value but is very missed. A small reward is offered for his safe return.
"he came into the pub where i work, the Red Lion in Ealing, but i had to refuse him a drink because he didnt have any ID. I then had to ask him to leave after he became abusive to some customers, last I saw i think he was walking in the direction of the bus stop"
