An Arizona man who refused to put down a huge kitchen knife stabbed himself in the neck after being tased by a cop and falling to the ground, bodycam video shows.

The incident unfolded last Tuesday when police were called to the scene of a “suspicious” house fire in Glendale, AZ Central reported.  

Officers arrived to find a man, who they later determined to be associated with the burning home, acting in an “odd” way.

The bodycam footage showed cops trying to keep the man away from the house fire in the moments before he brandished the kitchen knife.

“Holy s–t. Let me have the knife. Put the knife down,” an officer can be heard saying as soon as the man pulls it out.

The cop then points his Taser at the man as he repeatedly tells him to “put the knife down.”

The man falls to the ground after being tased as the cop lunges towards him, the footage shows.

“The knife is in his neck,” the officer can be heard saying.

The knife-wielding man initially refused to allow paramedics to treat him but was eventually taken to a hospital.

His condition wasn’t immediately known.

Cops haven’t released the man’s identity and said an investigation is still underway.
