SNP finance probe: Police seize luxury campervan in Fife

According to reports, the Niesmann + Bischoff motorhome – which normally sells for around £110,000 – was taken from outside a house belonging to Peter Murrell's 92-year-old mother.

The former SNP chief executive was arrested last Wednesday as part of an investigation into £660,000 raised specifically for a second independence referendum which may have been spent on other things.

He was released later that day pending further investigation.

It's been reported that the swoop came just minutes after Mr Murrell was taken into police custody and that, to the knowledge of neighbours, the motorhome had not moved in the two years it had been stationed outside the property.

The force spent two days searching the Glasgow home of Mr Murrell and the former First Minister.

They also searched the party's HQ in Edinburgh, taking a number of boxes away from the building. 

On Saturday afternoon, speaking for the first time since the arrest, Ms Sturgeon said the last few days had been difficult.

She told reporters outside that she understands “the scrutiny that comes on me as a public figure”, adding that she intends to “get on with life and my job as you would expect”.

She added that there is “nothing” she can say about the ongoing investigation into her party’s finances.

She said: “Well first off, there is obviously nothing I can say about the ongoing investigation.

“As much as there are things I may want to say, I’m not able to do so, other than to say that, as has been the case, there will continue to be full cooperation.

“The last few days have been obviously difficult, quite dramatic at times, but I understand that is part of a process.”

Police Scotland has said their investigation is ongoing.

An SNP spokesman said: “It would not be appropriate to comment on any live police investigation.

“The SNP has been co-operating fully with this investigation and will continue to do so.”
