Unruled abusive behaviour by the police

On the 24/11/2021 the police came to my mother's house with my wife where I slept with my daughter on that night. Upon arrival they demanded the child who was staying with me all the time since my wife neglected her. Once the gate was opened for them they started spraying everyone with pepper spray at home including the kids of 4 , 5 and 7 years. They kicked my mom's room door where my daughter was sleeping and they kept spraying at me n my daughter even when the child was crying they didnt stop spraying. They then forcefully take the child who didn't even want her mother. The door of the room is now broken n my mother is on Warfarin medication as well as Hypertension. They sprayed me everywhere on my body trying to impress my wife. Cause they were even swearing at me calling my mom's private parts. what kind of police do we have. They didnt have the badge on them. Even after taking my daughter they kept on beating me. remember we talking about my daughter that I didnt ***** but i was staying with her hence my wife took the boy. They came demanding the child without any document from the court and that is my daughter we talking about. The mother is abusive that's why the daughter doesnt want to stay with her. Even after explaining to the police what the mother is doing to the kids they forcefully take her without any right or permission. But why did they brake the doors , why did they spray the kids and my mother as well as the little kids. Why was I beaten? Is this how we should be treated by the people who sapose to protect us. But rather they only get impressed by seeing a lady's thighs then they decide they should do what they did to impress her? Justice need to be done. I will never rest untill justice is done against this police and their behaviour. Now I'm in pain by being beaten and pressed with the rifle on my neck.
