A man has been arrested on suspicion of attempted murder following the shooting of a teenage boy who remains critically ill.
The 16-year-old was found injured on London Road, Sheffield, at about 17:15 GMT on Monday and was taken to hospital.
South Yorkshire Police said a 26-year-old man had been arrested by Police Scotland in Aberdeen on Saturday night, along with a 23-year-old woman, who was being held on suspicion of assisting an offender.
Two boys, aged 15 and 16, were arrested on suspicion of conspiracy to commit murder earlier this week, but have since been released on bail.
Police said the victim remained in a critical condition in hospital.
A 40-year-old man, also arrested earlier this week on suspicion of assisting an offender, has been released on bail.
Det Ch Insp Emma Knight, from South Yorkshire Police, said officers were continuing to carry out reassurance patrols in the London Road area.
“This incident understandably caused a lot of concern and heartache in the local communities and our thoughts remain with the child’s family,” she said.
“He is 16 years of age and should have been looking forward to his future but now, his life has been put on pause as he remains in a critical condition following this horrific act of violence.”
Anyone with information is also asked to get in touch with police.
