ARMED police were called out to Croydon after reports of an air gun being fired from a house window on Saturday afternoon.
However, the officers found an unattended 11-year-old boy and six-year-old girl at the house on Alpha Road, Addiscombe just before 2.30pm.
One of the children had been throwing objects out of the window, but no air weapons were found.
A spokesman said: "Officers attended, and as is routine with calls of this nature, some of the officers that attended the scene were armed."
He said both children were looked after by police before being placed with a family member. Detectives from a Child Abuse Investigation Team, as well as Social Services, are investigating suspected child neglect.
No arrests have been made.
