Bomb, hostage threats against Qld school

Classes have resumed at a Gold Coast primary school put into lockdown after threatening graffiti was found scrawled on a classroom window.

A spokesperson for the Department of Education said classes resumed around 11am after the school was given the "all-clear" by Queensland police.

In an email to parents on Monday, Ashmore State School said the graffiti warned about bombing the school and threatened to "take one child hostage every day until they disappear".

A Facebook post from the school's P&C said parents were given the option of picking up their children, who were kept safe with teachers and staff on the oval.

Parent Bec Guy told AAP after reading the email she went straight to the school to pick up her three children.

She praised the teachers for keeping the students calm.

"(I'm) thankful for the lovely teachers who kept the kids happy and relaxed".

Queensland police say no suspicious people or packages have been found and the threats are being investigated.
