Mysterious markings that appeared on buildings in Thame are not targeting dog owners, police have said.

Officers moved to reassure people after 14 of the markings were found on house walls, driveways and gates in Thame between Thursday and Saturday.

Posts on social media have suggested the markings were left by criminals to flag up homes where a dog lives so that the pet can be stolen at a later date.

Police said the white marks are a chalk-like substance and have been found in small lines, and occasionally in V, circular or triangular shapes.

They have also been found in Aylesbury, Buckinghamshire.

Sgt Vicky Hoskin said: "There has been speculation on social media that the markings have been found only on homes where there is a pet dog, and this speculation has caused some concern amongst local dog owners.  

“We have had no information passed to us, and no evidence to would suggest that anyone is being targeted, or that the markings have anything to do with dog ownership.

“The Thame neighbourhood team have been regularly patrolling Lea Park since the markings were first reported to us in order that residents can speak to them if they are concerned.  

"Officers will continue with these local patrols, but there will be no further investigation into the markings."
