The Scottish National Party's treasurer Colin Beattie has been arrested in connection with a police investigation into the party’s finances.
Police Scotland said the 71 year-old has been taken into custody and is being questioned by detectives.
The arrest of Beattie, who also serves as an MSP for Midlothian North and Musselburgh, is the second in relation to the investigation into how more than £600,000 in donations to the party earmarked for an independence referendum had been used.
