Residents are being warned to lock their doors and windows following a spate of burglaries.
Police said burglars have raided several houses and stolen flat screen televisions, laptops, cash and other items.
The incidents happened in homes on Bold Street, Avenue Parade and Water Street, which are all within a small area in Accrington.
The police said the burglaries all happened overnight in the last two weeks and are linked.
Sergeant Stephanie Hurst has now sent out more officers to patrol the burglary hotspots.
Officers are also conducting leaflet drops and conducting door-to-door knocks to boost vigilance in the community.
Sgt Hurst said: “There is a clear pattern of burglaries in the Peel and Barnfield areas.
“Burglaries are happening overnight.
“Though most of the thefts originated from forced entry, on some occasions doors and windows had been left open for an intruder – so please remember to keep your homes secure too.
“We are doing all we can to find these perpetrators, nevertheless we would ask residents to keep their wits about them and look out for and report any suspicious activity.”
Sgt Hurst was also keen to remind residents the areas hadn’t suddenly become crime-ridden.
She added: “It’s not like we’ve got someone out burgling houses every night. We just want to draw residents’ attention to it and increase their awareness.
“We think the burglaries are linked. We want to catch who is doing it, prevent the crimes and detect what is happening.
“And we don’t want people to think they are living in a hard crime area, because they are not.”
Anyone with any information regarding the burglaries or who sees anything suspicious, can phone police on 101 or anonymously through Crimestoppers on 0800 555 111.
