It is now over a week since a Newcastle University student went missing after a night out.
Jason Fyles, 19, from Southport, was last seen in the early hours of last Thursday in the Sandyford area of the city.
Police are continuing to appeal for anyone with information to come forward.
They are keen to speak to a "Good Samaritan" who helped Jason on the night he disappeared.
Supt Andy McDyer said: "We still need to speak to the man who helped Jason and I would urge him to contact us as soon as possible."
The Good Samaritan is described as being around 20-years-old, 5ft 8", of stocky / athletic build, with short light blond or ginger hair.
Last night officers handed out hundreds of pictures of Jason to people socialising in the city centre, a week after he disappeared.
