Parents are being urged to tell their children about the dangers of playing in abandoned buildings.
It's after a child found shotgun cartridges while playing in a derelict house in Portadown.
The boy, who was playing with other children there, phoned his mum who alerted police.
In a social media post, officers praised the boy and his parents, but warned of the real dangers of playing on unsecure sites.
