A police hunt is underway for a man on the run following an attack in Sheffield.
Christopher Helliwell, aged 46, is wanted by South Yorkshire Police in connection with an assault in Woodhouse, in February, during a which a woman sustained a serious head injury.
Police believe he may hold vital information about the incident.
Acting Detective Sergeant Andy Miller said: “Helliwell is fully aware that he is wanted by police and that we are out looking for him. As a result, he is deliberately trying to avoid arrest.
“I’d ask that anyone who sees him, speaks to him, or who knows where he is to please contact us. If you see him, please don’t approach him but instead call 999."
Helliwell is known to regularly visit Longley in Sheffield as well as Treeton, Rotherham.
Anyone with information on his whereabouts should call South Yorkshire Police on 101.
