Police in Eckington and Dronfield are stepping up patrols and urging residents to lock their doors and hide car keys after a number of sneak-in burglaries in the area.
Over the past three weeks there have been seven burglaries reported to the police where offenders got into insecure homes and stolen, or tried to steal, car keys.
The most recent incidents took place in Eckington on Friday, January 1.
A set of keys were stolen from the back of a door to a property on Castle Hill at around 3.25pm.
And at 3.55pm on the same day, a woman at a house Osmund Road disturbed an offender who was trying to reach around the front door for the keys to her car.
The offender quickly left the area after hearing the woman, but it is believed he was wearing a red jacket.
DC Damian Lowe, of the local burglary unit, said: “Investigations are currently ongoing and we would urge anyone with information about these incidents to contact us.
“We are also asking residents to be more security conscious and to make sure that they make sure that they keep their doors locked, even if they are home, and that any sets of keys are kept out of sight and out of reach of doors, windows, letterboxes and cat flaps.”
Extra patrols are being carried out and officers from the safer neighbourhood policing team are holding events in Eckington on January 7 to offer advice on how to keep homes and vehicles secure.
They are set to take place between 1pm and 4pm at The Co-operative, Eckington Library and the swimming baths.
Anyone with information about the incidents should contact Derbyshire police on 101, or call Crimestoppers anonymously on 0800 555 111.
