A man indecently exposed himself to two teenagers in broad daylight.
At about 1.30pm last Tuesday, two 16-year-old girls were walking through Glossop town centre when they noticed a man following them.
As the girls approached John Street the man walked in front before exposing himself to them close to Pikes Lane.
The offender is described as tanned or mixed race, about 5ft 10in tall and aged in his late 20s to early 30s.
He was bald, clean shaven and had thick eyebrows.
He wore a dark blue t-shirt with a white logo on the front and knee-length grey jogging bottoms.
Witnesses or anyone with information should call Derbyshire police on 101 or Crimestoppers on 0800 555 111.
