The D.A. concluded Friday the cop did NOT put his knee on the man's neck during an incident that sparked outrage last weekend. The D.A. insists the cop in question put his knee on the man's head ... not his neck.

Martin said, "Based upon my review and the totality of the circumstances surrounding this event, I have concluded that there is absolutely no evidence to support filing criminal charges against either of the Allentown police officers involved in this incident."

He went on to say, "I am satisfied that given Mr. Borrero's obvious intoxication and his actions, he was clearly a danger to himself and potentially to others."

Martin said he assigned several detectives to investigate. He says the detectives interviewed the man and he revealed he was a heroin addict who ingested powder cocaine and did so just hours before the altercation.

As we reported ... a man was driving in Allentown Saturday when he saw cops trying to subdue the man. A few seconds into the video, the officer seems to employ the type of neck restraint that killed George Floyd. The police department had recently banned the use of chokeholds and other neck restraints.
