An Aum Shinrikyo member under arrest was recently hired as a contract employee by a corporation affiliated with the Science and Technology Agency and had been involved in the development of computer systems at the University of Tokyo's graduate school, police said Wednesday.

Prompted by the new revelation about Atushi Ogata, 45, who was arrested Tuesday for allegedly submitting a false resident registration document to a Tokyo ward office, police searched the astronomy laboratory at the university, also known as Todai, on Wednesday morning.

Police are also analyzing some 2,000 items confiscated from the cult's facilities, they said.
