CAPE CORAL, Fla -  Cape Coral police officer Michael Moore resigned late Thursday amid an investigation into whether he used excessive force.

The police department says Moore was fired because of his actions during a call in June.  He was also named in two other excessive force lawsuits.

Moore appealed his firing and the police union was backing his efforts to save his job, until Moore filed his letter of resignation.

Moore was with the department for five years.

Here is Moore's resignation letter in its entirety:

On Thursday, November 18th, 2010, at 2359 hours, I, Michael Moore, am resigning from the employment of the City of Cape Coral due to personal reasons. I would like to extend my appreciation to the City of Cape Coral for the past years of employment.
Thanks in advance,
Michael Moore
