A peeping Tom who used a camera disguised as a pen to photograph up a cabin attendant's skirt has avoided charges after Japanese prosecutors failed to decide which legal jurisdiction the plane was flying over at the time, reports said. The 34-year-old man stretched out his hand with thespy camera to take the shot while he sat in his seat, the Asahi news website said yesterday. He was arrested by police and admitted what he had done, saying he was "aroused by uniforms", the report added. The man was on a Japan Airlines flight from Takamatsu in the southwest of the country to Tokyo last month, according to an earlier report by Kyodo News. The police tentatively determined the photo was taken over the western prefecture of Hyogo based on witness accounts and their analysis of flight data, it said. But prosecutors said the photo could well have been taken when the plane was over neighbouring prefectures, Kyodo added. "Peeping Tom" offences typically fall under prefecture-level laws to prevent public nuisances and require prosecutors to state exact locations of the crime.
