A man has been arrested after a 10-year-old boy was found dead in a house in Coupar Angus.
Police have confirmed that an eight-year-old girl, discovered at the same property, has sustained serious and life-threatening injuries and is being treated at Ninewells Hospital.
Officers attended the home on Union Street after receiving a call from a member of the public at around 2.30am on Sunday.
They discovered the children and found an injured man nearby.
Chief Inspector Ian Scott said: “At this time, our thoughts are very much with the family and friends of the young boy who has died in this incident and with the young girl who remains in a serious condition in hospital.
“I can confirm that a 37-year-old man has been arrested in connection with this incident.
“Inquiries are ongoing however I believe this to have been an isolated and contained incident with no threat to the wider public.
“There will be a police presence at the scene for some time while we undertake our investigation and I would like to thank the local community for their patience whilst we carry out our work.
“There will be additional patrols by local community based officers in Coupar Angus to help provide some reassurance to the community.
“If anyone heard or saw anything in the Union Street area, who hasn’t already spoken with officers, I would ask that they call police on 101 (ref 0611 of 11 Nov) with details.”
