Cars belonging to holidaymakers who parked on streets near an airport have been vandalised.
The two vehicles were left on roads close to Luton Airport.
A windscreen and windows were smashed and the cars daubed with messages complaining about people not paying for airport parking.
Luton Council said it was consulting with residents about introducing parking permits in the areas affected.
Luton Airport said it would always urge passengers to use the onsite parking.
