In a statement released through police, Johnston’s partner, Sophie Quinn, said: “No amount of time will ever bring our Joe back, but we can try and move forward now that justice has been served.
“We can put this to bed and finally grieve as a family after these heart-breaking painful nine months.
“Joey will be forever loved, and missed by myself, his parents Tony and Michelle, his three beautiful children, and his other family and friends.”
Det Insp Mark Jenkins, of Dorset Police Major Crime Investigation Team, said: “Both collisions involved young men being pursued on electric motorbikes around residential streets in Bournemouth simply because of a dispute which had occurred between two groups of associates.
“We are pleased that Treadwell and Harrison are now behind bars and facing justice for their despicable offending.
“Our thoughts remain with Joey Johnstone’s partner, children, and the rest of his family and friends.”
