Police are appealing for women who have been approached by a scantily clad photographer to contact them.
The man has been asking women joggers in the Raywell and Ferriby areas to take snaps of him using a camera and tripod he carries while semi-naked.
It is believed the man has been seen in only a ski hat and sunglasses, a home made "mankini" and a thong.
A 58-year-old Hull man has been arrested in Welton Dale and released on conditional bail.
Detective Constable Garry Vincent from Beverley CID said: "I am requesting that any women who believe they may have been approached whilst out walking or jogging in the Raywell and Ferriby areas over the last two years, by a partially unclothed man carrying a camera and tripod who may have asked them if they could take their photograph, to please come forward."
Anyone with information is being asked to contact Humberside Police on 0845 6060222.http://www.thisishullandeastriding.co.uk/news/Appeal-victims-thong-wearing-man/article-2394410-detail/article.html
