A 40-year-old male customer at an internet cafe near Tokyo was arrested Friday night after holding a female worker hostage for more than 32 hours in a small room, police said.

The worker in her 20s was released with no visible injuries. Police officers broke the door's lock with special tools and stormed into the room after confirming the man had fallen asleep.

The suspect, identified as Kazutaka Hayashi, barricaded the 3-square-meter soundproof room but made no demands for money in exchange for the woman's release, according to investigative sources. He entered the cafe at around 10 a.m. Thursday.
