Police arrested a man on suspicion of attempted murder after a knife attack that left two people injured at Todaimae Station on Tokyo Metro's Namboku Line on Wednesday evening.

The suspect, 43-year-old Yoshitaka Toda, whose occupation is unknown, has remained silent during interrogation after being arrested at the scene, investigative sources said.

The victim, a 20-year-old male university student, told police he does not know Toda, and no prior connection has been found between them, police said.
