Nicola Sturgeon is in custody after being arrested in connection with the investigation into the Scottish National Party’s finances.
Scotland’s former first minister and ex-SNP leader was detained as a suspect and is currently being questioned by detectives.
A Police Scotland statement said: “A 52-year-old woman has today, Sunday, 11 June, 2023, been arrested as a suspect in connection with the ongoing investigation into the funding and finances of the Scottish National Party.”
“The woman is in custody and is being questioned by Police Scotland detectives.
“A report will be sent to the Crown Office and Procurator Fiscal Service.”
Scotland’s former first minister is the latest high-profile figure in the party to be detained as part of Police Scotland’s Operation Branchform into the whereabouts of £600,000 of funding that had been earmarked for a second independence vote.
It is understood there have been complaints the ringfenced cash may have been used improperly by being spent elsewhere.

Her arrest comes on the back of the detentions of party treasurer Colin Beattie and former party chief executive Peter Murrell – also Ms Sturgeon’s husband – who were both subsequently released without charge.
Police previously searched the SNP headquarters and Ms Sturgeon and Mr Murrell’s home as part of the investigation.
A luxury £100,000 motorhome was also seized from outside the home of Mr Murrell’s mother in Dunfermline, Fife.
The SNP has said it has been “cooperating fully” with the investigation and would “continue to do so”.
Ms Sturgeon’s arrest will intensify the scandal that has engulfed Scotland’s largest political party just months after she stood down as party leader and first minister in February.
The ongoing turmoil has overshadowed the new leadership of Humza Yousaf, who was elected to replace Ms Sturgeon in a bitter and divisive leadership race in March.
Mr Yousaf previously said he was unaware the SNP owned a £100,000 motorhome until he became party leader.
