A LIQUID that only shows up under ultra violet light was daubed on a number of cars in Woodville.
People living on Excelsior Drive noticed the sticky fluid and reported it to police.
A Spokesman for Derbyshire Police told the Mail: “We were called at 8pm on Wednesday to Excelsior Drive in Woodville after a number of people reported finding strange fluid on their property, fences and cars.
“The informant believes that it was done the evening of the day before.
“The fluid shows up under UV light. “Officers attended and checked it out and will be monitoring the situation.
“The fluid hasn’t caused damage to any of the property and has been washed off by the owners.
“We would urge anyone who sees suspicious activity in the area or who finds this kind of fluid on their property to call police straight away on 101.”
“We want to hear from anyone who has the same thing happen.”
It could not be confirmed why anybody would use this particular substance.
