Police raced to a Lapaha residence in Tongatapu this afternoon after reports that a woman was found unconscious.

A neighbour told Kaniva News she was surprised when she heard two Police vans coming down with their sirens on before they stopped at her neighbour.

A video clip apparently taken at the scene appears to show the moment Police were talking to people at the property before they carried a woman who was apparently lying unresponsive on the ground to one of the Police vans.

A person is overheard saying before the vans leaving the scene they would contact the family about the condition of the woman

The neighbour said on a post on Facebook Police took the unconscious woman to hospital.

The circumstances surrounding the incident are unknown. Police could not be reached for comment.
