A 13-year-old girl was approached by two men and raped in woodland near a war memorial in Angus.
Police have launched a manhunt after the teenager was subjected to the serious sexual assault in Kirriemuir.
Officers are looking for two men, described as white, both 6ft 2ins tall and with brown hair. They were between 25 and 37 years old and wore sweatshirts and jogging bottoms.
Police have said the incident, which happened near to the quarry and war memorial, took place in the early evening between Monday, January 13, and Friday, March 20.
Detective sergeant Kevin Mollison said: “This was a traumatising incident for the young teenage girl and we are giving her the necessary support she needs at this time and will continue to do so.
“Our enquiries are at an early stage but we do believe it was an isolated incident.
“As part of our investigation, officers will be carrying out door to door enquiries in the area we are keen to speak to anyone who may be a regular dog walker in the area and have information that could help.
“In addition, local uniformed officers will provide an increased presence in the area in the days ahead and I would encourage members of the public who have information or concerns to please approach these officers.”
Anyone with information is asked to contact police on 101.
