Police have found that the suspect in Thursday's deadly arson attack on an animation studio in Kyoto visited an internet cafe a few days before the incident.
Shinji Aoba is suspected of setting fire to Kyoto Animation's number one studio, leaving 34 people dead and 34 injured.
The 41-year-old suspect suffered serious burns. Police plan to arrest him once his condition improves.
Police say that, after visiting the cafe in Kyoto City, Aoba bought gas cans and a lighter at a hardware store in Uji City.
Police believe that Aoba then went to inspect the studio and other company facilities in advance.
Security camera footage from near Kyoto Animation headquarters show a man resembling Aoba pushing a cart the day before the attack.
Police plan to analyze personal computers in the cafe as part of their efforts to determine his motive.
