A rise in bomb threats has left US government buildings on alert.
This follows a spate of falsely reported shootings by public officials.
The bomb hoaxes played out on government buildings have seen major evacuations across several states.
The FBI has begun work to determine the sources of what has been labelled as “evil intent”.
The hoax is known as ‘swatting’ where a large police presence or a SWAT team show up to a false alarm.
