A man exposed himself to woman as she walked her dog at Gog Magog Hills on Thursday, February 8.
At approximately 4pm he emerged from the trees and signalled for the woman to look over before dropping his trousers and exposing his penis.
He is described to have been white, approximately 30 years old, wearing a dark, hooded tracksuit.
DC Mark Hodgson said: “This incident follows a pattern of six similar instances throughout 2017 in which a male has exposed himself in public.
“Although these incidents have not involved any form of assault or threat, they have left the victims shaken and hesitant to return to the scene of the exposure.
“We would like to ask members of the public to be vigilant in reporting offences of this nature and would ask anyone who has any information to come forward.”
