A Japanese student who climbed and slipped over a railing while trying to get a better view of the Niagara Falls is presumed dead after her body has still not been recovered.

On Sunday, the 19-year-old student who studied in Toronto climbed over a rail overlooking the Canadian side of the falls. She was holding an umbrella in one hand and fell 80 feet into the gushing edge of the falls that swept her away, the Global Post reported. The incident was captured on security cameras.

Searchers have not yet found the body but have presumed the student dead. During the search a male body was found at the base of the falls but it has not yet been identified.

"The public is reminded that climbing over this wall is clearly dangerous and is prohibited by the Niagara Parks Act and its regulations," Niagara Parks Police Chief Doug Kane warned.

"Millions of visitors have viewed the scenic Niagara falls and the Niagara River gorge while respecting the safety wall without incident."

"We get about 11 million people a year here who view that annually - this is the first occurrence of this nature that I can recall," Kane told the Toronto Star.

Since 1903 only seven deaths at the falls including people have been deemed as accidents, and only one of these survived in 1960, the Toronto Star reported.

Every year there are between 20-25 cases of suicide that take place at the falls.
