A 12-year-old boy was in a stable condition after he was hit in a drive-by shooting.
The child was in a group of youngsters and adults gathered in Errington Road, in the Arbourthorne area of Sheffield, at around 3.45pm on Sunday, when a white car drove past and a gunman opened fire.
Police were called and they found the boy had suffered an injury to his leg.
He was taken to hospital for treatment and remained in a stable condition, police said.
Detective Inspector Denise Booth said: “Specialist officers have been in the area this afternoon and evening, examining the scene and speaking to witnesses as we work to piece together the exact circumstances of this incident, what led to it and to identify those responsible.
“What we know so far is that the boy was with a group of other people, both children and adults, in the Errington Road area when a white car is said to have driven past, firing shots out of the window.
“The car left the area heading towards East Bank Road.
“In the early stages of the investigation, as we continue to gather evidence, we are exploring all lines of enquiry as to the motive of the incident.
“I understand and appreciate the concern this news will cause within the local community particularly given the victim’s age, and to help provide some reassurance to residents, we will have an increased presence in the area tonight and over the coming days.
“This matter is an absolute priority for us and it’s imperative that anyone with information or concerns speaks to an officer.”
