74-year-old charged over sending a bullet to Barnaby Joyce's office

A 74-year-old man has been charged after sending a bullet to Barnaby Joyce's office during the middle of the New England byelection campaign.

Armidale man Neville Newman will face court on charges of stalking and using a carriage service to cause offence to the Deputy Prime Minister.

A separate bullet was found alongside a threatening note at a school where voters were about to cast their ballots 10 days before the polls opened, but NSW Police have not confirmed if the incidents are related.

The note warned there would be a shooting on December 2, the date on which the New England byelection was held.

It came a month after Mr Newman allegedly sent a bullet to Mr Joyce's Tamworth electorate office along with concerns about Queensland's Adani coal mine.

Mr Newman is also alleged to have made a threatening phone call to a home on the night before Christmas Eve.

"Investigators commenced inquiries into a threatening phone call that was made to a home about 3.20pm on Saturday 23 December 2017," NSW Police said in a statement.

Mr Joyce was forced into a byelection after the High Court ruled his nomination in 2016 was invalid due to his New Zealand dual citizenship.

In a thumping byelection victory in early December, Mr Joyce won with a primary vote of 64 per cent, up from 52.3 per cent at the last federal election.
