An incident at a luxury Scots hotel which saw at 11 people requiring medical assistance was caused by chemicals being used in the spa.
Emergency crews raced to the McDonald Inchyra Hotel in Polmont, Falkirk, at around 7.30pm on Sunday and seven people were taken to hospital after the building was evacuated.
It followed reports of a “stronger than normal smell of chlorine from the swimming pool.”
On Monday afternoon, a Police Scotland spokesperson said: “Around 7.40pm on Sunday, 26 September, officers were called to assist at a hotel in Grange Road, Grangemouth, following a report of a chemical leak.
“Following a multi-agency response it was discovered that the incident was a result of chemicals being used in the spa area.
“A number of people were evacuated from the hotel as a precaution, but later returned.”
Seven people were taken to hospital and at least another four were treated at the scene.
The Record previously told that many of those evacuated were wedding guests, while others were at the hotel for a ‘sweet sixteen’ birthday party.
They waited in the car park as a police chief arrives and explained the situation to them before they were allowed to re-enter.
Paramedics also asked anyone who had used the leisure facilities to come forward for treatment in a designated area.
The guests were then accommodated in another wing of the hotel while the fire service examined the scene.
A Scottish Ambulance Service spokesperson said: “We received a call at 7.34pm to attend an incident at Inchyra Grange Hotel in Polmont.
"We dispatched several resources to the scene and seven patients were transported to hospital.”
An NHS Forth Valley spokesperson said: "A small number of patients were taken to hospital for assessment last night, but they have all been discharged."
A spokesperson for Macdonald Hotels said: “Following reports of a stronger than normal smell of chlorine from the swimming pool at the Inchyra Hotel in Grangemouth, guests were initially evacuated to the car park, then accommodated in another wing of the hotel as a precaution whilst the fire brigade carried out investigations into the cause.
"We are pleased to report that, following checks, guests were allowed back into the hotel and normal service was resumed.”
A DJ at the 16th birthday party in one of the smaller suites, Kyle Maclachan, told the Record he had just started playing his first song of the night when the fire alarm started going off.
He said the hotel staff were very quick to respond by taking the guests out to the car park and that the fire service had arrived and police were taping off the area within 20 minutes.
A fire service spokesperson said: “Operations Control mobilised two appliances and specialist resources to the scene, where crews assisted partners by making the area safe.
“Eleven casualties were in the care of the Scottish Ambulance Service and crews have now left the scene.”
