The former first minister was detained this morning and held in custody while she was quizzed for seven hours by detectives. Police Scotland confirmed she was released at 5.24pm this afternoon, after being arrested at 10.09am this morning.
The 52-year-old stood down as both SNP leader and first minister in March this year, since when there have been several dramatic developments in the probe into her party’s spending.
In a shock statement tonight on Twitter this evening, Ms Sturgeon said: ‘I know beyond doubt that I am in fact innocent of any wrongdoing.’
‘To find myself in the situation I did today when I am certain I have committed no offence is both a shock and deeply distressing’, she added.
