Stirling MP Alyn Smith was forced to alert police after he received an email of a threatening nature last week.
The SNP MP says that he was contacted on Monday (February 1) evening.
The ominous communication left Mr Smith concerned and he raised the matter with Police Scotland.
Following the email, Mr Smith told the Observer: “On Monday evening, I received a threatening email, the nature of which merited alerting the police to it.
“Sadly, it’s not unusual for politicians to receive abuse, but this email was particularly threatening and I felt that the police needed to be involved for the protection of my team as well as for my own protection.
“I don’t normally publicise abuse, as I often judge it’s better not to give a louder voice to it. But the nature of this incident is different and I think it’s right that people should be aware.
“I’m very grateful for the support given to my team and I by Police Scotland, who I trust to take whatever action is necessary and appropriate in response.”
A spokesperson for Police Scotland said: “We were notified of an online communication, and following enquiries no criminality was established.”
