A child has been found dead at a home in rural Perthshire while another fights for her life.
The 10-year-old boy was discovered at a home in Coupar Angus at around 2:30am when police were called to the scene.
An eight-year-old girl was also found with life threatening injuries.
A 37-year-old man has been arrested following the incident in the early hours of this morning.
It is believed a man was found injured in the street before a member of the public called police.
They then broke into the home and found the children.
Chief Inspector Ian Scott, of Police Scotland, 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.
‘Enquiries 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 Scotland on 101 (ref 0611 of 11 Nov) with details.’
The girl, eight, has been taken to Ninewells Hospital in Dundee.
