Torrential rain has forced search parties looking for Jamie Taggart to interrupt their search in the hills of northern Vietnam.
Weather and finally a broken ankle suffered by a team member forced the group back down to recover at Sapa.
Jamie (41), of Cove on the Rosneath Peninsula, has now been missing for nearly six weeks.
The weather is not expected to improve until Monday, and meanwhile an appeal for funds has been issued by the friends of Linn Gardens.
Ian Sinclair is liaising with the the party led by Phil Hoolihan of Ethos Travel in Sapa, Vietnam.
“Phil is arranging a meeting with vice director, Mr Hao, of the National Park Authorities to discuss voluntary labour and will apply for permission to search the area more extensively, to cover more than two days’ distance from where Jamie was dropped off,” he said.
“Areas such as gullies and gorges will be priorities and this must be done through the local police.
“The proposal is to use 20-25 Hmong men, forest rangers plus any voluntary fit individuals. “
The estimated cost is expected to between £1,600 and £2,000 and Jamie’s friends are seeking funds to continue the search.
Contributions towards the cost of the search can be made by a cheque made payable to “Friends of the Linn” with the words, written on the back, “for Jamie”.
The cheque should be sent to Mrs Rie Bellamy, treasurer, Friends of the Linn, Portkil House, Kilcreggan, Helensburgh, G84 0LF.
If a payment is to be made through a bank the details are as follows: Friends of the Linn, Bank of Scotland, Helensburgh Branch, Sort code 800831, Account number 00704064 – again the words “for Jamie” should be used.
Police have checked all villages in the area for Jamie, of Linn Gardens in Cove.
The retained firefighter went missing on November 1 while on a plant-hunting expedition, but his family did not realise he was missing until four weeks later.
