A man is being hunted by railway police after groping a foreign woman on a crowded Taiwan Railway train, in a case that highlights how often such incidents go unreported.

• A male passenger repeatedly pressed and rubbed himself against a foreign woman standing in front of him on a commuter train from Banqiao toward Taichung.
• Another passenger filmed the harassment as evidence, then went with the woman to a police station to help her file a report.
• The suspect got off the train at Taoyuan before he could be stopped.
• Railway police say they have identified a specific suspect and are working to arrest him.

Outlook: An arrest looks likely soon given the video evidence and the witness statement, and the case is set to renew pressure for tighter security on packed commuter trains.
