Police have arrested a man in relation to a robbery at a Christchurch bank on Monday.
Detective Damon Wells said a 22-year-old unemployed Christchurch man was interviewed at a property today and arrested.
The man will remain in police custody overnight and will appear in the Christchurch District Court tomorrow charged with robbery.
Wells said it was "very good to have an arrest".
"It's good for bank staff as well," he said.
The robber was dubbed "the smiling robber" after he walked into the ANZ Woolston branch about 3.20pm on Monday and secured a small amount of money.
Security images were released of the alleged robbery showing the man smiling and making no attempt to hide his face.
Police said the man had "an item" in his hand while he carried out the robbery but would not disclose what it was.
Wells said the arrest was made possible through a combination of police inquiries and information from the public.
Police were called to the bank after security alarms were activated.
