Sleights and Briggswath residents have been left in fearing for their property after a spate of burglaries recently.
The thefts all occurred on Monday, when three properties in the villages were broken into.
Items of jewellery were taken during two of the offences, which took place on The Carrs at Briggswath.
The third burglary was on Coach Road at Sleights.
PC David Anderson from Whitby Police Station said: “These offences were committed during the night, which is very concerning.”
PC Anderson explanied that crimes such as these are rare, and figures show that between January and May this year there had been just five reported thefts in the Sleights and Briggswath area.
However, he added the victims had been hit hard by these latest thefts.
He said: “In once instance the elderly victim has had various items of family jewellery stolen, which as well as financial value also hold great sentimental value.
“I would therefore urge anyone that may have seen anything, no matter how insignificant it may seem, or has any information in relation to this matter to get in touch.”
In light of the burglaries, police officers have been making enquiries in the area and had increased the number of reassurance patrols operating around the villages.
“I would like to remind householders to be security conscious, remember to lock doors and windows, and hide valuables were possible”, added PC Anderson.
Whitby Police are keen to catch those responsible and any information about this or any other offence will be dealt with in confidence.
