A woman who approached two 11-year-old girls in Kettering yesterday (Thursday, July 2) is being urged to contact police.
The incident happened between about 5.15pm and 5.45pm when the two girls were walking along Cedar Road.
A woman, who was in a dark green car, approached and spoke to them.
As the girls did not know the woman, they did not speak to her and went into a nearby shop.
Police are appealing for witnesses and, in particular, are urging the woman who spoke to the girls to contact them.
She is described as white, in her mid-30s, with shoulder-length brown hair and was the only person in the car.
Officers are also asking parents and guardians to remind their children of the appropriate safety advice with regard to strangers, encouraging them to tell a parent, teacher or police officer if they are approached.
Witnesses, or anyone with information, are asked to call Northamptonshire Police on 101.
Alternatively, they can call the independent charity Crimestoppers anonymously on 0800 555 111 or use the anonymous online form at www.crimestoppers-uk.org.
