A search is underway after a man has gone missing after boarding a flight to Switzerland.
Fergus McInnes, 51, boarded an Easyjet flight to Geneva Airport on Tuesday 9 September at 9.35am, which was scheduled to land at 12.50pm.
The University of Edinburgh research fellow was due to attend a science conference there but did not check into his hotel or go to the conference.
He has not boarded his scheduled return flight and his whereabouts remain unknown.
He is described as white, 5ft 7ins, slim and with ginger hair.
According to the BBC, Mr McInnes, from St Leonard's Bank in Newington, works at the University of Edinburgh's School of Informatics.
PC Philip Wright told the Scotsman: "We are very keen to hear from Fergus or from anyone who has information to his whereabouts, as we are increasingly concerned for his welfare.
"Anyone who has any information is urged to contact Police Scotland on 101 or Crimestoppers on 0800 555 111."
