Police have said sorry to a man who was hit by a stone thrown by yobs while he waited for a response to a 999 call.
Police were called to reports of boys throwing stones at a home on the Grange estate, Kettering, at 6pm last Sunday.
The victim, who uses a walking stick, was subsequently hit by a stone, but it took another 999 call for officers to arrive, 40 minutes later.
A police spokesman said: “Following his complaint the victim was contacted by the control room inspector, who apologised for the delay and acknowledged that, because of the vulnerability felt by the victim, a higher priority response should have been considered at the outset.
“All calls are graded and an emergency response will be given if a life is at risk, a crime is in progress or there is a serious traffic incident.
“The vulnerability of the caller or victim is also taken into consideration. However, this did not happen on this occasion. Feedback has been given to call handlers.”
A 13-year-old boy admitted the offence and was given a youth caution.
