Police were called to a quiet suburban street following the sudden death of a teenage girl.
Officers were called to Osprey Rise at Piperdam around 9am on Tuesday.
An 18-year-old was found dead inside a property.
One eyewitness said an ambulance, three police cars and CID officers were in attendance.
The witness said he spotted the police activity as he drove past the scene of the incident.
A spokesman for Police Scotland said the death is currently being treated as “unexplained”.
One police vehicle was still parked in the cul-de-sac shortly before midday.
A resident, who declined to be named, said he had also spotted the emergency crews arrive in the street.
He added: “I saw the police turning on to Osprey Rise, however, I had no idea what was going on.
“It must have been just before 9.30am that I saw the three police vehicles and an ambulance outside an address.
“It is very quiet around this area – even more so this morning because the kids are back at school.”
Another resident said she had just returned home when she saw a police vehicle parked in the street.
She said: “When I arrived at the street I noticed a police 4×4, but I couldn’t see any officers.
“I don’t think the vast majority of residents know what has happened.
“While I was there it looked like an unmarked van arrived and left shortly after noon.”
Some neighbours living close to the house declined to comment.
Other residents in the area said they were unaware of the police activity.
A spokesman for the force said: “Police Scotland has attended at an address on Osprey Rise, Piperdam, Fowlis, in response to the sudden death of an 18-year-old girl.
“The death is currently being treated as unexplained, and inquiries are ongoing.”
A Scottish Ambulance Service spokesman said: “We received a call at 8.54am to attend an incident in Osprey Rise, Piperdam.
“We dispatched one ambulance to the scene.”
