A 56-year-old man who has admitted to trespassing into a Tokyo school attended by Prince Hisahito is suspected of cutting some of the electric wiring connected to the campus surveillance camera system to avoid being recorded, investigative sources said Tuesday.
Pruning shears were discovered on the premises of Ochanomizu University after two knives were found on 12-year-old Prince Hisahito's classroom desk in its affiliate junior high school around 11 a.m. Friday, according to police.
The police believe the man, who identified himself as Kaoru Hasegawa after his arrest Monday, avoided the university's main gate when he entered the junior school.
