Cyberpunk cop book

Falling in love with the cyberpunk genre (akira, edgerunners, cyberpunk 2077, cowboy bebop) and now i want to read a good cyberpunk book. First and foremost the cop doesn't have to be a detective but work his way up to it. Secondly I'm looking for more of a serpico by the books cops he can bend the rules sometimes but it has to be for the greater good. Finally gotta have plenty of gunfighting and fist fights with the gangsters, serial killers, etc. Also he doesn't have to be a ladies man but at least let him have a girlfriend at some point
