An architect has been arrested on suspicion of forging an ID card to help a 19-year-old youth gain access to a photo session with all-girl pop group AKB48, police said.

Makoto Iijima, 48, a certified class-1 architect who lives in Fuji, Shizuoka Prefecture, stands accused of forging an official document with a seal. Tokyo police have also reported the 19-year-old resident of Tokyo to prosecutors over the case.

According to investigators, the youth bought a ticket to the AKB48 photo session under the name of another person. As he needed matching ID, he reportedly asked Iijima to change the name and address on his high school student card to that listed on the ticket, and Iijima did so at his home in mid-May.

The two have reportedly admitted to the allegations.
