SAO PAULO, June 13 (Xinhua) -- A 21-year-old woman died Saturday in Brazil after being released from a platform about 40 meters high during a rope-jump activity without a safety line attached, local authorities said.

The incident occurred at the Ponte do Esqueleto bridge in Limeira, a city in southeastern Sao Paulo state.

During the activity, instructors failed to attach the safety equipment needed to prevent the victim from hitting the ground, authorities said.

Videos shared on social media appeared to show several people carrying the victim to the jumping point. Seconds after she was released, shouts of alarm could be heard as people warned that the safety rope was missing.

Authorities said two suspects tried to flee into a nearby wooded area after the accident. They were later found during a search operation. In all, six people were detained and taken for questioning by police.

Firefighters and emergency medical teams were sent to the scene, but the woman was pronounced dead at the site of the accident. ■
