An Ohio man was arrested last week for attacking a teen he said was raping a 5-year-old, police said.

Richard Adams, 20, walked into a room of his Eastlake, Ohio, home last Thursday and said he saw a 17-year-old raping a 5-year-old boy, WEWS reported.

“I kinda blacked out,” Adams told Cleveland's Fox 8. “I saw a 17-year-old molesting a 5-year-old. I wanted to help the young boy and that was all I was thinking about was getting it stopped.”
