Police in Bristol recently received an emergency call alerting them to sounds of a woman in distress.
According to the caller the wails were coming from a local beauty area which is known as a notorious suicide spot.

Given the terrain, a search by foot wasn't possible - so a helicopter from the National Police Air Service was dispatched to find the source of the chilling screams on Sunday.

1650hrs Avon Gorge searching for person who sounded in distress. We may have found the culprit! pic.twitter.com/1GY3WCRMgg— NPAS Filton (@NPAS_Filton) January 24, 2016
NPAS Filton posted a picture of the goat on Twitter with the caption: "1650hrs Avon Gorge searching for person who sounded in distress. We may have found the culprit!"
Ollie Dismore, from the NPAS, told the BBC: "A National Police Air Service (NPAS) helicopter was yesterday involved in a response to a 999 call at the Avon Gorge in Bristol."
"As the difficult nature of the terrain meant that a search on foot would not be possible by the local Avon and Somerset police force, they called in the police helicopter to take on the search and NPAS Filton responded to the call."
A spokesman for the NPAS said: "The police appreciate the efforts of this caller as they do all callers who support their work by alerting them to incidents which they may otherwise not be made aware of."
