Two women were struck when an aerial camera fell in the Olympic Park on Monday afternoon.
Reports indicate that Flavio Oliveira was just getting out of a handball match with his nephew when he heard the wires come crashing to the ground.
He said the cable whipped against two girls, hitting one of them in the neck.
Pollyanna Padua, an Olympic worker who was working nearby, said the cable fell and injured two adult women.
She said they were given first aid at the site of the crash but described the injuries as "light." Padua said the women were transported to a local hospital.
Games officials placed barricades around the crash site, which is at the entrance of Arena Carioca 2, which hosts wrestling and judo.
People crowded around the scene and stopped along an elevated walkway to take pictures.
The incident occurred at about 2:30 p.m. local time.
Weather in Olympic Park was sunny and hot on Monday, though there were strong gusts of wind that knocked over chairs near the Main Press Center.
