Man calls police for help after finding his stepson committed suicide -- Police help by assaulting him

Dixon said he arrived home to find his stepson dead inside his garage. The 24-year-old had committed suicide.

When police and emergency crews arrived, Dixon said paramedics took over the rescue effort.

"I left the garage, walked to the front door. One of the police officers came up behind me, grabbed my arm, and said, 'You need to sit down.' I jerked my arm away from him and said, 'Don't touch me.' That's all I said to the man, and he tackled me," Dixon said.

Dixon said other officers then joined in and two allegedly held him down, while two others punched him in the face.
