Two teenage boys had to be rescued after a “reverse bungee” ride failed at Winter Wonderland in London.
The pair were left suspended in a cage in the air after “one of the bungee cords attached to the cage snapped”, according to the Metropolitan Police.
Staff members at the Christmas event in Hyde Park had managed to lower the cage and free the boys before police arrived.
London Fire Brigade confirmed on Twitter it had attended the incident, but had not needed to respond.
No injuries were reported.
The force said a preliminary inspection indicated a “technical fault within a sealed gear box” used to control the release of the elastic cord and steel wire rope.
Winter Wonderland event organisers have been approached for comment.
