Vinicius Da Silva and Marta Rosenthal were returning home from a day of fishing in the River Tocantis when they felt a bump in one of the tires. Thinking he had a flat, Vinicius stopped the vehicle and went to check.
He could not find anything wrong with the tire but suddenly heard Marta screaming and saw her pointing to the right side of the road. There, only a few meters away, hovering over the water was a metallic object with small windows along its edge.
Standing outside the object on a ledge was a humanoid figure of about 1.30 meters in height.
The figure was holding something resembling a hose and was apparently sucking water from the river and into the craft. After about two minutes the humanoid pulled up the hose from the river and re-entered the object. The craft then became very bright and shot away horizontally into the sky.
