WANTED MAN: Police had appealed for information about Harlem Langley.

Police have arrested a 24-year-old man involved in a firearm incident with police in Mangere, Auckland, earlier tonight.

Harlem Langley was on the run for a few hours earlier this evening after an altercation with police at a Yates Rd address.

Counties Manukau police issued a statement about 11:10pm saying he had been arrested and charged with assaulting police. He is due to appear in Manukau District Court on Friday.

MICHAEL FIELD/ Fairfax NZ GUARDED SITE: Armed police outside the Mangere house.

Earlier police said three officers went to a Mangere address about 6.40pm to make an arrest but were set upon by family members of the wanted man.

Police were threatened with what they believe was a firearm. The potential for danger led one officer to fire a single shot.

No-one is believed to have been hit or injured by the shot. Another man was arrested at the scene earlier.

Police left the Yates Rd house and cordoned it off until the Armed Offenders Squad arrived.

A full investigation is under way and the Independent Police Conduct Authority has also been informed.
