Have you found a grey patterned backpack containing an A4 diary and paperwork?

The bag was left on a train from Honor oak park to London bridge on 3rd Nov afternoon. Met the train at london bridge and was no longer there. Also checked with station staff at Brockley, New cross gate and London bridge and nothing handed in.

Possible that someone picked it up and has dumped it outside a station or nearby once they realised nothing of value inside. If you have seen this please PM me with whereabouts.

Thanks!
