Detectives investigating yesterday's shooting incident in Meersbrook Park have issued a detailed description of the man they are looking for.
The man is described as white, between 23-30 years of age and of slim build with dark, scruffy shoulder length hair.
He is believed to be around 5ft 10in tall, and is reported to be wearing a black coat, khaki t-shirt and was carrying a rucksack.
Chief Superintendent Stuart Barton of South Yorkshire Police said the shooting appeared at this stage to be an 'isolated incident'.
He said: “We are still looking for the offender and it is common to have an armed response for a time until we know exactly what has happened.
“We are also working with the family who have kindly offered a reward for information."
Mr Barton added that the injured man appears now to have been shot with a pellet gun and that his injury was not as serious as first thought.
He also thanked the public for the support they have given the investigation so far and added police would remain at the park for reassurance for some time.
Police were called to the park at around 6.30pm last night following reports that a man had been shot in the face.
This morning, a 22-year-old man was reported to be in a serious but stable condition in hospital.
Sheffield Heeley MP, Louise Haigh, also issued a statement about the incident.
She said: “I know local residents are of course concerned about the incident that occurred last night in Meersbrook Park.
"As I currently understand an investigation is ongoing following a 22-year-old suffering injuries consistent with an airgun wound. He has been taken to hospital and remains in a serious but stable condition.
"Police have described the offender as being white, slim, wearing a camouflage or khaki jacket and carrying a black rucksack. He is said to have long, greasy hair and a wispy beard.
"No arrests have yet been made but detectives are carrying out enquiries and are keen to hear from anyone who may have information about the incident.
"If you did see or hear anything which may be of use, please contact South Yorkshire Police on 101, quoting incident number 773 of 26 April 2018.”
