Tribal Huk president Jamie Pink was put in mental care on the weekend after his arrest on firearms charges.

It's understood that although Pink did not resist arrest, he was highly agitated and police sought assessment at Waikato Hospital's Henry Bennett Centre.

His arrest and charges relate to guns found in a vehicle that was left at the Waikato Times on Labour Monday.

Pink's troubles come after he declared war on P in Ngaruawahia on October 13 at a community meeting.

Pink said last week that he got rid of 14 P houses.

Calls to Pink on Monday went unanswered.

Gang sources told Stuff that Pink had refused to sleep during his crusade and had become "erratic".

"It got pretty bad when he went to roll one of the dealers. He parked up at his house rocked on in like he f...... owned it. [name withdrawn] just come out and shot at the truck. It was like he had a death wish."

The man, who is an associate, said Pink's recent activity had really taken its toll.

"When he says he's going to do something then he is going to do it till the end. No sleep, just do it until the end. That's his problem though, when he does things he does it 100 per cent and he almost takes himself out in the process," he said.

"I know he will be protected. He has to be now – he has made big enemies and they won't let what happened go.

"If you're going to smash your way into P houses that are paying rent to a bigger outside gang, you have to have a screw loose, but his heart is in the right place, eh. I get his kaupapa, I just get scared for his safety and the safety of the crew. The other gang is not one you can really afford to f... with."

Gang sources claimed Pink's truck was also "shot to s..." in the rural area of Waingaro by an outside gang who had local interests in the small Waikato town.

Pink had earlier said he didn't shoot up his own truck.

The source said he wished that Pink had shot up his own truck, that way they could get out of a much larger issue that was looming.

"I wish that was the f...... truth because the reality is, that shot-up truck signifies a much larger war on the way.

Police said no complaint had been laid with them in relation to the alleged shooting of the vehicle.

Pink is due to appear at the Hamilton District Court on November 2.
