Police say two men dressed as Santa Claus have robbed a guard at Stockholm's royal castle of his assault rifle, according to AP. Police spokesman Anders Krook says the duo attacked the guard in the early hours of Friday morning, entering his security zone by the castle and beating him up before fleeing the scene with his loaded AK5 rifle. A colleague came to the guard's aid and he was not seriously injured. Krook says the robbers were dressed in Santa hats and masks. They made no attempt to enter the castle, which is not the royal family's residence. There are no suspects in the case.
