Police were suspicious when a 21-year-old Inverness man told them his name after officers were called to a disturbance in Culloden last month.
Inverness Sheriff Court was told Benjamin Clark gave them the name of another man when he was being quizzed about the incident in MacLean Court, on October 12.
Constables were able to establish from a Police National Computer photograph that Clark was not who he said he was.
Clark, of MacGillivray Court, Culloden, was arrested and he threatened police officers and their families.
Fiscal depute Michelle Molley told Sheriff Chris Dickson: “He said: ‘I will bite you on your face I am going to do you all in. I will find you and kill your children.’”
Clark admitted threatening behaviour, attempting to pervert the course of justice and malicious damage.
He was also appearing for sentence on a charge of hindering police during a drugs search of him in November 15 last year at a property in Glendoe Terrace.
Ms Molley said Clark briefly escaped after a piece of brown material was found on him.
Sentence was deferred until November 28 for a drug treatment and testing order assessment on the request of defence solicitor Duncan Henderson.
