Haunted swings

An out-of-control playground swing has spooked families and police in Argentina.

The swing rocks back and forwards without being touched - and anxious parents have decided the playground must be haunted.

In an attempt to explain the swing's mysterious movement, police called in physics professors. But even they have been unable to explain the why the swing keeps moving.

Residents claim the middle swing in a playground in the north-eastern town of Firmat can keep moving continuously for ten days before suddenly coming to a halt.

Teacher Maria de Silva Agustina said one child had nicknamed the area the "Blair Witch Playground".
