ARMED intruders burst into a house and threatened a woman who was home with two young children.
A knife was pointed at her and the thieves escaped with a haul of jewellery worth £4,000.
The masked raiders knocked at the door of the house on Norwood Road in Birkby at 7pm last night.
When the woman in her early 30s opened the door, two men forced their way in and held a knife against her chest.
They demanded her gold and took the victim upstairs where they stole two jewellery boxes.
The wooden boxes, which are both covered in a red material, contained a large amount of jewellery.
The thieves picked up the boxes and fled.
Both were described as African-Caribbean men, between 5ft 6in and 5ft 8in tall. They wore balaclavas, dark trousers and dark gloves.
The jewellery included a 24-carat gold link necklace, a pair of ear-rings and four gold bracelets all with red and green beads, 24 Asian gold bangles, a gold ring with the initials MS engraved on it, a 24-carat gold necklace with gold stones and four gold rings.
Pc Allison Cook, of Huddersfield CID, said: "Did anyone see the men in the area either before the aggravated burglary or escaping afterwards?
"Did they get in a car?"
