Fire destroys barn near Moniaive Primary School

Police are keen to trace a group of youths seen in the area around the time of the fire

An investigation has been launched into a fire which destroyed a large hay shed at a farm next to a village school in south west Scotland.

Fire crews spent the night tackling the blaze which was discovered near Moniaive Primary School at about 17:00 on Sunday.

Police said they keen to trace a group of youths seen in the area.

No-one was injured, but about 50 tonnes of hay and a number of farm vehicles were destroyed.

The total damage was estimated to be worth more than £32,000.

Residents said the blaze had effectively destroyed a slice of local history.

The building was once used as a goods shed for the former Cairn Valley Railway.
