Derek Chauvin, the former police officer seen with his knee on George Floyd’s neck, had 18 prior complaints filed with Minneapolis Police Department's (MPD) Internal Affairs, according to MPD.
It's not clear what the internal affairs complaints were for and no detail was provided by MPD.
Only two of the 18 complaints against Chauvin were "closed with discipline," according to a MPD internal affairs public summary.
The "discipline issued" column listed a letter of reprimand for each of the two complaints.
Former officer Tou Thao had six complaints filed with internal affairs, one of which was still open, the summary said. The other five were closed without discipline.
Former Minneapolis police officers J Alexander Kueng and Thomas Lane had no complaints filed, according to a MPD internal affairs public summary.
CNN has reached out to attorneys representing the officers for comment.
