… Six-foot tall Torvald Alexander, 38, was wearing a red cape and the thunder god’s silver-winged helmet when he spotted the raider in his front room rifling through a desk.
Mr Alexander, who runs building firm Alexander & Summers in Edinburgh, Scotland, said the burglar threw himself out of a first floor window of his £350,000 home in the Inverleith area of the city after being caught red handed.
Mr Alexander said: “As soon as he saw me his eyes went wide with terror.
“He looked like he had had a few drinks and decided to do a late night break in, but he hadn’t counted on the God of Thunder living here.”
He added: “I had just got back from a fancy dress New Year’s party and because I have a Norwegian name I decided to go as Thor.
“It took ages making the cape, helmet and breast plate, and I must admit it was a bit chilly walking home, but when I saw that guy I just went mad and charged at him, my cape flying behind me.
“I think if I had had Thor’s hammer with me I might have scared him to death.”
