Marlborough Police are investigating reports of four vehicles being scratched in the Avebury area last week causing hundreds of pounds worth of damage.
All the vehicles appear to have been targeted during daylight hours on Wednesday, February 26.
PC David Tippetts, who is the community beat manager for the area, said: "It is unusual for this type of offence to not only be committed in this area but to be committed during daylight.
"This mindless behaviour has caused distress to the victims on top of the financial cost of repairs."
Anyone with any information is asked to contact police on 101 or Crimestoppers on 0800 555 111.
