An Invercargill teenager who allegedly sent nationwide bomb threats has been granted bail despite strong police opposition.

Police say the boy, who has automatic name suppression, sent threatening emails to several organisations, including the Department of Corrections and Southland Boys’ High School.

The teenager appeared in the Invercargill Youth Court on Tuesday after being arrested on Monday night and charged with two counts of threatening to do grievous bodily harm/threats to kill.

His arrest followed an investigation by police into threats sent to educational and public sites across New Zealand.
