FORT MYERS, FL--AFort Myers Police officer has been kicked off the force after hitting a man in the head multiple times.

The Chief of police says officer Trevor Lehman used excessive force during this arrest back in February.

Dramatic dash cam video shows the February arrest of 27 year old Chaylon McClary.

Officer lehman throws the first punch across McClary's face as he starts resisting.

"He's being struck in the head and it's very apparent and it's very clear," said FMPD Chief Doug Baker.

Further in to the dash cam video, Lehman throws three more punches to the head.

It is violence that ChiefBaker says goes against the department's use of force policy.

"The defendant in this case is not striking or not attacking the officer," said Baker.

Use of force consultant Dave Grossi  was a consultant in this case and we asked him about the different levels of force and when officers can use them.

Grossi says the body is broken down in to three zones..

"We call them green zones, yellow zones and red zones," said Grossi.

The green zones are large muscle groups like calves and thighs.

Grossi says if the person under arrest starts resisting, officers are allowed to use force in those areas.

If the defendant continues to resist, Grossi says officers can start to use more force in the yellow zones with hands, fists or the baton.

"The yellow areas of the body are areas where bone is located such as wrists, the elbow the knee," said Grossi.

But officers can only go after the red zone, anything above the collar bone, if they need to use deadly force.

AndChief Baker says McClary was not attacking lehman and the blows to the head were uncalled for.

"At the end of the day, that is not a conduct that I believe is appropriate," said Baker.

Lehman's attorney told us they plan to file an appeal and a grievance against FMPD.

He says they didn't have the proper cause to fire Lehman and believes he used the force necessary.
