One nearby resident, Coralie, who didn't want her surname used, lives on neighbouring Brennan Place and said there was "a large volley of gunfire" with a lot of police around.
She said among the "red and blue lights" she could hear police officers yelling: "Armed police, put the gun down! Put your hands out the window, anyone else in the vehicle put your hands out the window!"
Coralie said this was repeated multiple times before a final "they're not moving" and then silence.
Just before midnight, she said "cop cars and lights are still sitting quiet" on the street.
A Hamilton resident, who didn't want her named used, said she heard multiple gunshots that she initially thought were fireworks.
"It sounded like they kept shooting but were firing blanks. It was very loud though."
Bird said a scene guard would remain in place overnight and members of the public were asked to avoid the area.
"Inquiries into the circumstances of the incident are ongoing."
