A student from Japan is presumed dead after being swept over Niagara Falls on Sunday night.
The woman, in her 20s, climbed on to a pillar overlooking the Canadian side of the falls and slipped, police have said.
A Canadian tourist, Kari Wilson, described seeing the woman straddling the railing.
Doug Kane, Chief of the Niagara Parks Police, said accidents of this kind were ''pretty rare''.
