A "very high risk" sex offender who went on an armed rampage weeks after he was freed from prison was jailed on Wednesday for more than five years.
Kenneth Gibson attacked two strangers in the streets of Edinburgh after pulling a knife on police officers before shouting: "Do you want me to take a hostage? I will murder someone."
Gibson told the female police officer: "You are alright due to being a burd but I am going to kill you", before pointing to her male colleague.
