Three teenagers have been arrested after an incident in Adelaide's inner-southern suburbs which left a mother and son with minor stab wounds.
A 15-year-old Elizabeth Downs boy, a 14-year-old Flinders Park boy and 13-year-old Ferryden Park boy were charged with illegal interference and theft.
SA Police said a 47-year-old woman woke up about 4:40am Sunday morning after hearing the noise of three people breaking into her car on Young Street in Unley.
They allege the boys ran towards King William Road and she chased them, joined by her young son.
The woman and her son were then involved in an altercation and received non-life-threatening stab wounds.
The victims were taken to hospital, and police located a knife nearby.
The two older boys were charged with breaching bail.
The 13-year-old appeared in the Adelaide Youth Court yesterday and was remanded in custody.
The other two boys have been refused bail to appear in the Adelaide Youth Court.
