BRISBANE, June 13 - Upper Coomera State College received two threats via social media, and staff put the school into lockdown once in the morning and again in the afternoon before police determined the threats were a hoax.

A 36-year-old woman from Upper Coomera was charged on Wednesday with using a carriage service to menace or harass, wilful disturbance at an educational facility and fraud, and will face the Southport Magistrates Court on June 28.
