NIAGARA FALLS, NY (WKBW) -- Eyewitnesses fishing near the power plant along the Robert Moses Parkway reported seeing a man in the water around 7 a.m. Tuesday morning.
Reports say they saw a man wearing a life vest, attempting to swim from the US to the Canadian shoreline.
Police on both sides of the border responded and apprehended the man when he got out of the water, though reports indicated there was a second person involved, who officials feared was still in the water.
Authorities launched a search of the gorge, enlisting Erie County Sheriff's Air One chopper to make several low altitude passes along the gorge.
By mid-morning, the search was called off, and police believe the second person involved was waiting on the Canadian shore to greet the swimmer when he arrived.
Police in Canada have now taken over the investigation, and continue to look for an Hispanic male, who is suspected to be the second person involved in the illegal border crossing.
