My brother is currently a prisoner in Trenton, NJ. I was just informed that he was handcuffed and beaten by four officers. Until he began BLEEDING

I was informed my brother had an altercation with another inmate. The officers broke up the fight. They asked my brother to get on his knees and he complied. They cuffed him and the four officers started beating and kicking him until his face started to bleed and swell. Although he did have a fight with an inmate, he did not deserve that abuse from a gang of officers (He never resisted) And now he’s in the hole for 90 days. Please advise me if you can be of any assistance. I would greatly appreciate it
