In the UK there is the crime of 'Theft by finding' [0] when you find something you think is abandoned and take it, but do not do anything to determine if it really was abandoned, as opposed to lost, unattended, etc. The Wikipedia article suggests similar offences exist elsewhere...
Usually that process involves turning the property in to the government, and waiting some period of time for the original owner to claim it. If it is not claimed, it would become yours.
I don't know of any law that requires property on public space to be locked. There may be laws saying you can't leave property in public for more than a certain amount of time, but I am pretty sure none of those would allow anyone to just take the property.
