Wiltshire Police are appealing for Matthew Hobin from Swindon to come forward as they who they would like to speak to him about harassment offences.
Gloucestershire Police also have questions of a similar nature.
Hobin has been seen recently in the Penhill and Haydon End areas of Swindon but he could currently be anywhere in the town. He also has a keen interest in angling, so might be spotted in places where this activity takes place.
Detective Sergeant Troy Smith said: “If you see this man, please do not approach him. Instead dial 999 and give his exact location, direction of travel and description of clothing and any items he is carrying.
“Anyone with information should call Wiltshire Police on 101 or Crimestoppers.”
