At least 10 people have been injured by piranhas in the same Argentine river where a similar attack by the carnivorous fish occurred last month. The vicious creatures, known as palometas, have been attacking bathers since Thursday at the Parana River in Rosario, which is 186 miles north-east of Buenos Aires. Seventy people were bitten by the shoal of meat-eating fish in late December as they attempted to cool off from the unusually high summer temperatures. Vicious: A shoal of sharp-toothed palometas have been blamed for recent attacks on swimmers in Argentina During that attack, a seven-year-old girl lost part of a finger, while other swimmers suffered deep cuts to their ankles, fingers and hands.
