Police are looking for a man who allegedly groped a woman on a train Tuesday before jumping off the platform at JR Ikebukuro Station and running away along the railway tracks.
According to the Ikebukuro Police Station, the man, who is believed to be in his 40s, allegedly shoved the female victim in her 20s at the station at around 9 a.m. after she accused him of groping her inside a train on the JR Saikyo Line.
The train had departed Akabane Station in Tokyo's Kita Ward and was running southbound to central Tokyo.
Video footage of the man running away was taken by another passenger and widely shared on social media.
The alleged perpetrator is about 165-170 cm tall, police said.
The incident led to a halt in Saikyo Line and Yamanote Line trains in both directions during the morning rush hour, affecting 32,000 passengers, according to media reports.
On Monday a man was reportedly seen running on the tracks after being accused of groping at JR Ochanomizu Station in Tokyo.
