Rescuers in Taichung are still searching a fast-flowing river for a man who witnesses saw fall from Dongshi Bridge, and confusion over his identity is slowing the effort.

• Witnesses reported an elderly man sitting on the bridge pier before falling into the water late yesterday afternoon.
• Firefighters searched through the night in strong currents and found no one; the search resumed this morning.
• Police found an electric bicycle, a raincoat and a helmet left at the scene and traced the owner's family.
• Identity is still unconfirmed — witnesses described a man over 70, while the bike's owner is said to be in his 50s.

Outlook: Search teams are expected to keep working the river downstream until the man is found and his identity confirmed.
