Police have launched a public appeal to find missing university student Megan Roberts, who was last seen in the early hours partying in a nightclub.
The York St John University student, who is 20 years old, was reported missing by her mother on Monday, after a friend raised the alarm.
Megan, who is originally from Wetherby, West Yorkshire, was last seen at around 2am in Popworld on George Hudson Street, in York city centre on 23 January.
According to police: "Nobody has heard from Megan since, which is very out of character and officers are very concerned for her safety."
She is described as around 5ft 6in tall, of medium build with long dark brown hair. When she was last seen she was wearing a cream knee length dress which had large brown and orange flowers on it and black plimsoll type shoes.
Concerned friends and family have posted on the student's Facebook wall asking for information, with one offering to put posters up of the missing woman in local pubs. Another added: "Megan Roberts hasn't been seen in the past few days, if anyone knows or hears anything from her let her friends know or get in contact with the police. Thankyou xxx"
Anyone with any information is asked to contact North Yorkshire Police on 101, select option 1 and pass information to the Force Control Room.
