According to the Chiba branch of East Japan Railway, a woman accused Shinya Ieda, a company employee living in Funabashi City, of groping her inside carriage of the Sobu Line upon its arrival at JR Makuharihongo Station at around 9:10 p.m.
As station staff waited for police to arrive, Ieda fled from an office and leaped onto the track bed at around 9:50 p.m. He then climbed an electric supply tower.
At 11:40 p.m., rescue personnel coaxed Ieda to surrender. He was subsequently arrested by officers from the Chiba-Nishi Police Station on suspicion of trespassing.
According to JR East, the incident caused 31 trains to be delayed for nearly three hours, inconveniencing about 30,000 passengers.
