Voters are being warned to look after their postal votes during the election period or face being locked up.
The elections are being held on 3 May
A new campaign has been launched by West Midlands Police to try to prevent election fraud.
Posters and leaflets have been produced highlighting how voters should take care of their vote and the consequences of not doing so.
The leaflets are being distributed across the force area in the run up to the elections on 3 May.
Officers are giving voters this advice:
Look after your vote
Make sure your postal vote arrives safely - do not give it to anybody else
Do not let anybody steal your vote
If you commit election fraud the consequences are the same as any other offence - you will get a criminal conviction
Lock away your vote or you could find yourself locked up
Assistant Chief Constable David Shaw said: "There is little evidence of fraud on a major scale but, as always, by promoting best practice and learning from previous experiences we can reduce the opportunity from occurring.
"We are keen to educate the community on how to look after their vote but also to warn them of the consequences of committing election fraud."
