A man has reportedly discharged a firearm in Wellington CBD early this morning.

According to police, it was reported the man was heard yelling before the firearm was discharged near the Sirocco Apartments on Church Street. He was then seen walking up some stairs at the end of Church Street, leading up to The Terrace.

Several witnesses who had heard the male yelling and the firearm being discharged, saw the male later enter an apartment building on The Terrace.

Police cordoned this address and waited for AOS to arrive. A short section of The Terrace was closed for nearly two hours while the police cordon was in place.

AOS later arrested a male at the address, who was there with a female associate. The 35 year old was taken in to custody without incident and will be appearing in the Wellington District Court on Monday on firearms related charges.

No one was injured and at this stage it isn't thought that any property was damaged as a result of the firearm being discharged. It is believed that two shots were discharged, possibly from a shotgun.

A firearm has not yet been located and Wellington Police will continue to search for this in the morning.
