A 16-year-old boy was arrested after the car he was driving ploughed into the wall of a house, seriously injuring two teenage girls as they walked along the road with friends. The teenager was confined after the vehicle, believed to have been stolen, veered onto the pavement in Longsight, Manchester. A group of four girls were walking along Elsdon Road when the car crashed into three of them. The vehicle then drove over a garden bush and smashed into the wall of a house. Two girls, both aged 16, were seriously injured in the crash and a third was left with bruising. The two seriously injured teenagers were taken to the Manchester Royal Infirmary, with one suffering a broken arm and the other a fractured hip. Police were called to the scene and a 16-year-old boy was arrested on suspicion of theft of a motor vehicle and driving above the legal limit of a controlled drug. Shocked eyewitnesses reported hearing a "loud bang" and came rushing out of their houses and saw the aftermath of the smash.
