The family, friends and clubmates of Belvoir CC cricketer Euan Coulthard are appealing for help to find the missing Durham University student.
Euan was reported missing by a concerned friend after several failed attempts to make contact.
He started the night at an Italian restaurant in Saddler Street, before moving on to Love Shack in the Walkergate area of Durham, where he was last seen leaving alone at around midnight.
Inspector Dave Coxon, Durham Police, said: “We have serious concerns for Euan’s welfare as there has been no trace of him since the early hours of this morning.
“He hasn’t responded to any attempts to contact him and his phone has not been traced.”
Anyone with information should contact police on 101.
