A convicted stalker who took a knife to his ex-wife’s home told police he had it because he wanted to murder her new partner.
The woman called the police after she became concerned that ex-husband Francis Haldane was carrying a blade.
Haldane had previously been convicted of stalking and threatening the woman - and that call prompted officers to race to his home.
They found him with a kitchen knife in his jacket pocket.
At interview Haldane told officers: “I was going to jump on the train to Glasgow and stab the guy she is seeing - I want to kill him.”
Fiscal depute Eilidh Robertson told Dundee Sheriff Court: “He added that he had intended to kill the new partner and do them in.
“He said he had seen them together previously and if he saw them again he would kill him.
“He was volatile and agitated and frequently raising his voice.
“His presentation was, frankly, very alarming.”
Haldane, 40, a prisoner at HMP Perth, pleaded guilty on indictment to charges of carrying an offensive weapon and behaving in a threatening or abusive manner likely to cause fear and alarm.
The offence took place on June 15 this year at addresses in Arbroath, and at the local police office.
Defence solicitor Nick Whelan said: “Reports will be required as he’s currently on a community payback order.”
Sheriff Alistair Carmichael deferred sentence until next month for social work background reports.
He said: “You will be remanded in custody meantime.”
