Do you recognise these people in Exeter?
CCTV images have been released of a group of people police would like to talk to.
They're potential witnesses who atteneded the Arena Night Club on New Years' Eve and who may have spoken to the victim.
The first incident occurred during the early hours of New Years Day.
Police are also renewing their appeal to trace a missing White ‘River Island’ short sleeve shirt, and a white long sleeve top, which is fleece lined and has a zip up hooded top, which is still outstanding.
Officers believe that the clothing was discarded in the Clifton/Belmont area of the city.
During the second incident which occurred during the early hours of Sunday 9th January, the victim visited the pubs and nightclubs in the Exeter City area.
The offence occurred sometime after he left the Club during the early hours of Sunday, but the exact location has yet to be identified, although areas of interest are from the city centre to Western Way and the Bull Meadow Park area.
