Two people were burned in an acid attack at a Tokyo subway station and the assailant is still at large, police and local media said on Wednesday.
The attack took place Tuesday evening at Shirokane Takanawa station in an upscale district of Tokyo, as the opening ceremony of the Paralympic Games took place under tight security in the capital.
One of the victims, a 22-year-old businessman, suffered burns to his face after the suspect sprayed him with liquid on an escalator, a police spokesperson told AFP.
Public broadcaster NHK said the man was seriously injured by the liquid, which he called sulfuric acid.
A 34-year-old woman also fell and reportedly suffered minor burns to her legs.
The middle-aged suspect is still at large, said police, who are patrolling the area in an attempt to locate him.
Violent crime is relatively rare in Japan, which has strict gun laws, although there are occasional attacks involving other weapons.
During the Olympics earlier in August, 10 people were injured, including one seriously, in a stabbing attack on a commuter train in Tokyo.
The suspect later surrendered after fleeing the scene.
About 60,000 police officers are deployed for the Olympics and Paralympics, according to Japanese media.
