Christopher Brahney death: Police seek seven witnesses
Police investigating Stone Roses fan Christopher Brahney's death want to speak to seven people who used an alleyway where he was last seen alive.
The 22-year-old's body was found in the Manchester Ship Canal at Salford Quays, 10 days after he went missing following the band's gig at Heaton Park.
Greater Manchester Police has released footage tracing his journey on 30 June.
Officers reviewing CCTV identified the four women and three men as possible witnesses to Mr Brahney's death.
A spokesman said the seven were in three groups and may have information about how Mr Brahney died.
The first two women, who were filmed in the passageway at 00:32 BST, were described as both white and in their "late teens to early 20s". One had a bag and was wearing "a dark long sleeved top and black trilby type hat", while the other was wearing a "dark hooded top and had long hair".
The second group, captured on CCTV at 00:35 BST, were described being "three white men aged between 18 and 25, with short hair".
The third pair, seen at 06:28 BST, were said to be "two white women in their 20s". One was described as having "tied brown hair, a burnt orange jacket and blue jeans", while the other was described as wearing a "black padded jacket with hood up".
