Shocking footage of an arrest involving pepper spray and a dog in NZ

A routine traffic stop escalated into a man being pepper sprayed, wrestled to the ground by officers, and having a police dog maul his leg.
The young man was in a car driven by his girlfriend when he said they were pulled over just as they stopped for petrol in Porirua, New Zealand.
According to the man's girlfriend's sister, he got out of the car to buy cigarettes from the service station and ignored orders by a policeman to get back in the car.
The man's girlfriend's sister claimed the officer then sprayed his face with pepper spray as he walked towards the service window.
He said the spray did not kick in until he arrived at the window and the video begins as he is clutching his face in pain as the policeman stands by.
'He's going to be fine, as soon as he starts playing the game I'll give him a spray that makes it not hurt,' the officer was heard telling on of the women who went to help.
'He just pepper sprayed me for no reason,' the man said repeatedly. 'You've got no control, you don't own me.'
The man then ran around the building pursued by the officer before burying his head in his girlfriend's shoulder on the other side.
By now at least three more police cars had arrived at the scene, with one officer leading a police dog towards him.
They surrounded him and ripped him from his girlfriend's grasp in an attempt to arrest him, but when he resisted they tackled him to the ground.
'Let go of me, I did nothing!' he screamed as he was set upon by a police dog that ripped one of the legs clean off his pants.
The sisters and two female friends who were also present became increasingly upset throughout the video, repeatedly pleading with police to leave the man alone and accusing them of 'brutality'.
'If that cop was properly trained that whole situation should of been avoided, he was not angry or aggressive he just didn't listen and get back in the car,' the girlfriend's sister said on Thursday.
'At no point did he threaten or act aggressively, the only aggressive one was that cop who cant handle a simple situation without escalating it.'
The woman claimed he had a 'chunk of flesh ripped out' of his leg, a damaged eye socket and extensive bruising, along with his thumb being numb for a week after the incident from the handcuffs.
The man was charged with obstructing police, resisting police and two counts of assault on a police officer and will face court next week.
He filed a formal complaint to the Independent Police Conduct Authority alleging excessive force, but admitted to ignoring the officer's request to stay in the car.
He wants the assaulting police charges dropped and the use of force investigated, hopefully with the help of the service station's CCTV.
'We can confirm that a range of tactical options were deployed,' Kapiti-Mana area commander Inspector Tracey Thompson said, but did not confirm the use of pepper spray.
'While we have not been able to review the video mentioned, it is important to note that, as is often the case with brief video clips of this nature, it does not necessarily provide a full picture of what occurred prior to the event being filmed.
'As this matter is now before the courts, police are unable to comment further.'
