Input: The victim, a 21-year-old musician known as K or K-Dogg, was walking to the bus stop from his job at Southmead Hospital on 22 July. Police said it was being treated as racially-aggravated due to the language used by the car occupants. The 23-year-old man was arrested on Monday and released under investigation. Three other men, two aged 18 and a 22 year old, have also been released under investigation. A fundraising page to help the musician has raised more than £55,000 - 10 times its original target.
