A MAN will face court early next year after allegedly threatening a Maitland school during a phone call.
Police will allege the man made the call to an insurance company early on Tuesday.
Central Hunter detectives investigated the matter, arresting a 40-year-old man at his Thornton home.
He was taken to Maitland Police Station and charged with using a carriage service to menace or harass.
The man received conditional bail and is due to appear on January 14.
The Newcastle Herald earlier reported that students and teachers were briefly locked in their classes at Maitland Grossmann High School yesterday due to a security scare.
A NSW Police spokesman said the class lockdown occurred about 11.45am, with no access to the school.
The Department of Education and Training confirmed students were originally kept in classrooms under a lockdown procedure.
A swimming carnival organised for yesterday afternoon continued.
