800 - 774 3373 good luck and I feel so sorry for you because IAB in my experience CORRUPT which is why I am suing. http://nypdnewcommission.blogspot.com/2013/11/ray-kelly-nypd-internal-affairs.html
Warning in my opinion Internal Affairs is corrupt and will not investigate police corruption unless the Feds are involved.
If you are contacting the NYPD's Internal Affairs document all calls you can record any conversation you want in NYC because you need one party consent and you are the one party and document EVERYTHING because I found IAB is uber corrupt and you can SUE internal affairs.
The NYPD and all police on a federal level do not have to investigate in they don't feel like it but guess what Internal Affairs has to investigate police corruption so you can sue and I recommend you do until we get the Federal Laws changed that hold the police accountable.
