A man apparently holding a knife on a Yamanote Line train at JR Shinjuku Station was apprehended by police on Sunday after officers rushed to the scene following an emergency call, media reports said.
When police arrived, a knife was placed on a seat on the train, which had stopped at the station, with no signs that the man had been wielding it, the Mainichi Shimbun reported.
The incident led a crowd of passengers to evacuate in a panic, causing two men to suffer injuries after falling over, NHK quoted firefighters as saying.
According to investigators, the man claimed to be a cook and had been carrying the knife wrapped in a towel from his workplace. He said the knife was exposed when the towel fell off, NHK reported.
Yamanote Line services were suspended for about 20 minutes from around 4 p.m. to confirm safety. The line resumed services at around 4:20 p.m., but there were still some delays as of Sunday evening.
