Death Threat To Former Labour Deputy
Labour's Anas Sarwar has received a death threat on his answering machine.
The message threatening to shoot the former Scottish Labour deputy leader was left on the machine of his Glasgow office between April 8 and 10.
Scottish Labour said the matter has been reported to police.
Scottish Labour Deputy Leader Kezia Dugdale said: "These types of threats have no place in our society. No-one, politician or otherwise, should have to face threats of violence. What has it come to when people seeking to be part of the democratic process face threats of this nature?
"Anas Sarwar has a family who will rightly be concerned and staff who should, at all times, be able to go to work without fear of violence.
"In the face of threats we have to stand together and unite in our condemnation of this vile and disgusting behaviour. Anas Sarwar is a popular local figure and this sort of threat will not deter him.''
Police Scotland said they had no comment at this time.
Scottish Labour leader Jim Murphy tweeted: "Nobody should have to put up with vile threats like this. @AnasSarwar won't be deterred.''
There will be extra body search, ticket checks and bag restrictions.
Army personnel will be stationed at 12 military and civil nuclear sites in Scotland.
Police say the shopkeeper has been left badly shaken.
