Counter Terrorism police have arrested a man at Hamilton over alleged extremist activity online.
Detectives began inquiries earlier this week after finding concerning posts on social media containing extreme right wing views.
When violent threats were made online, officers arrested the 43-year-old man near Cleary and Beaumont Streets shortly after 5:30 Thursday afternoon.
He's been charged with using a carriage service for harassment and is due to face Newcastle Local Court on Friday.
A mobile phone seized from the man will undergo forensic examination.
Police are encouraging anyone with information about extremist activity or threats to the community to come forward no matter how insignificant the information may seem.
