Two police cars sped down the main street, sirens blaring, at about 9.40am to arrest the man.

“The man assaulted the bank manager and possibly another customer after the bank closed his account,” police said. 

“He was arrested at the scene.”

Police said the man had “mental health issues”.

Westpac Bank has told customers it would remain closed for the rest of the day due to an “incident”. 

The man has not yet been charged.
