Five people have been hurt, some badly, after a restaurant balcony collapsed.
The incident happened at the Casa hotel and restaurant on Elland Road in Brighouse, West Yorkshire.
A West Yorkshire Police spokesman said: "Some of those injured are believed to be serious."
Emergency services were called at around noon and said some details of the incident have yet to emerge.
West Yorkshire fire brigade said firefighters were currently at the scene. A fire spokesman added: "We have reports of five casualties."
One person was airlifted to Leeds General Infirmary with head injuries, a spokesman for Yorkshire Air Ambulance said. Other casualties are believed to have been taken to hospital in Huddersfield by road.
The balcony is believed to have been a decked area on the outside of the hotel, which is used as a Mediterranean restaurant and events venue.
A spokesman for Yorkshire Ambulance Service NHS Trust said five ambulances, a doctor and a specially-trained hazardous area response team were also sent to the scene.
The spokesman said: "Ambulance clinicians provided treatment at the scene and five adults have been taken to hospital for further care.
"One male patient has been airlifted to Leeds General Infirmary and four female patients have been transported by land ambulance to Huddersfield Royal Infirmary. All sustained serious injuries but none are believed to be life-threatening at this time."
