Three people questioned over the murder of a man stabbed to death at the side of a road have been released.
Two men, aged 26 and 29, were released under investigation while a 17-year-old boy was bailed until 30 October.
A fourth man was arrested in connection with possessing a bladed article, and also released under investigation.
The stabbing happened on Brandon Road.
