A 27-year-old woman was the victim of a serious sex attack in Corby on Monday (March 31).
She was pushing her bicycle along the footpath in Oakley Road, near Lidl supermarket, at 11.30pm when she was approached by a man who dragged her into bushes near Shannon Court and assaulted her.
Police are warning women in the town to be vigilant when out at night and to avoid walking alone.
The woman was walking away from town centre when the attack happened.
A police spokesman said: “The man spoke to her and made sexual advances, which were rebuffed.
“He dragged the woman into the bushes beside an alleyway near Shannon Court and the Lyvedon Way roundabout and assaulted her.
“The offender was disturbed by a member of the public who chased him away.”
The attacker is white, slim and in his early 20s. He was clean shaven, with small eyes and short brown hair and was wearing a light grey hooded top and grey tracksuit bottoms.
Detective Inspector Ali Reynolds said: “We know there were several people in the town that night and we would like to speak to anyone who was in or near Oakley Road around the time of the assault.
“We’re particularly keen to speak to anyone who may have seen someone running away from the area or know anyone who fits the description who was out in Corby on Monday night.
“We would also urge people to be vigilant when out and about at night and to avoid walking alone.”
