Suicide support charity probe.
Cops are investigating Neil Gillies, who walked out on the Inverness-based Suicide Awareness Group last December.
He was helping out the charity, which was formed after several young suicides in the area.
Gillies and his wife Flora had already set up the Highlands and Islands Support Group for Grieving Families after their son Kevin, 23, was run over by a taxi on Skye on Christmas Eve, 1999.
SAG were left with no funds after the split with Gillies and were forced to close their officeMembers claim the charity are now owed several thousand pounds by him.
The Office of the Scottish Charity Regulator are also probing a feud between SAG and the HISGGF over claims that the HISGGF owes SAG pounds 9500.
Police say they could also look at that matter, but that it would take several months to complete the inquiry.
Highland MSP Mary Scanlon, who helped support SAG, was interviewed by police earlier this week.
But Detective Sergeant Eddie Ross said: 'She is absolutely not implicated in any wrongdoing.
'We were speaking to her as a potential witness.'
SAG member George Campbell said yesterday: 'We are still there to help families affected by suicide, but with no funds it is difficult to do any outreach work
