Steven Harper, 38, was on a cycling journey from Scotland to India when he disappeared more than a month ago. According to the last message he sent to his family he was in Roquebrune-Cap-Martin and had fallen ill after eating mushrooms he had foraged.

His brother Dale posted on social media: ““His last photos are from Monaco, France (sic) where we believe he stayed the night on a hill. From what we know so far, Steven had his bike and bank card stolen along with his passport in early November.

“His last message on the 23rd of November said he had ingested a potentially lethal mushroom while foraging for food and we have not heard from him since. This has only come to my attention in the last 24 hours and I’ve been too distraught to write this.”

Dale told BBC Scotland: “Steven said he had been throwing up but he felt better… But it was radio silence from then. No one has been able to get a hold of him since and we don’t know if he is living with a debilitated body, if something has happened with the mushrooms he ate, where he slept.

“He had almost everything taken from him in Nice. It’s not unusual not to see Steven for long periods, but he had an itinerary and gives pretty regular updates on his movements.”

Interpol and Police forces from France, Monaco and Italy have been alerted to the Scot’s disappearance.

A spokesperson for the UK Foreign, Commonwealth and Development Office added: “We are supporting the family of a British man and are in contact with the local authorities.”
