A MAN has been jailed after repeatedly threatening to massacre colleagues at a charity call centre - claiming he wanted to sneak in an AK-47 and rig the fire exits with bombs to blow up escapees.

Samuel Howitt told colleagues he knew exactly what type of ammunition would cause maximum damage if he shot them - and claimed he knew how to make bombs.

Howitt, who was working for R Fundraising in Dunfermline raising funds for charities such as The Samaritans and Save The Children, left colleagues "scared and intimidated".

He later made a string of racist comments, telling a colleagues he wanted to join the army so he could "shoot Taliban and Pakis".

Sheriff Charles Macnair QC told Howitt, at Cupar Sheriff Court, that his actions were "frightening" and gave him a 200-day jail sentence.
