Tokyo police on Tuesday arrested a 42-year-old man from the suburb of Musashino on suspicion of involvement in a string of arson attacks along railway lines in the capital.
They seized musician Izaya Noda, 42, after an individual was seen apparently trying to set an East Japan Railway Co. electricity substation on fire on Aug. 23. It was one of several such incidents during August and September, some of which disrupted train services and caused damage.
The Metropolitan Police Department said Noda admitted causing the Aug. 23 fire but denied obstructing business.
