At least 12 people have been attacked by piranhas on a beach in western Brazil, Globo News reported, in the first piranha attacks recorded in the area.

Brazilian authorities said the swimmers were attacked at Daveron beach in the western city of Caceres.

Roselene Fereira, 45, was nipped on her toe by a piranha Sunday.

"It was all over in minutes. I felt a sharp pain in my foot and when I looked, I had a huge wound on my toe and it bled a lot. Everyone ran out of the water and I panicked," she said. "I was with my granddaughter playing in the shallows ... I just know I'll never get in the river [again]."

A sign was later put up on the beach warning swimmers to take care when entering the water.
