Police are appealing for witnesses after a man in his 20s approached a group of three schoolgirls in suspicious circumstances this morning (Tuesday).
Shortly before 8.30am, the man approached three girls in Kettering Road, Rothwell.
The girls became concerned and ran off.
A police spokesman said: “We are trying to establish the facts of exactly what happened this morning and what caused the girls to become afraid.
“We know that this was a busy time on a busy road and it is likely that other people may have seen something, and we would urge them to contact us.
“The man in question is described as being around 5ft 7ins tall with short, dark brown hair.
“He was wearing a blue Adidas jacket, jeans and a dark coloured rucksack.
“The same man may have been at the bus stop outside Tesco in the town centre.
“We don’t want to alarm anyone and the children involved were not harmed in any way.”
