Frank Ocean says he'll "choose sanity" and let his fight with Chris Brown go.

"No criminal charges. No civil lawsuit," Ocean said on his Tumblr pageSaturday night.

"As a child, I thought if someone jumped me it would result in me murdering or mutilating a man," the post said.

"But as a man i am not a killer. I'm an artist and a modern person. I'll choose sanity."

Authorities are investigating the January 27 brawl, in which Brown is accused of punching an unnamed victim on Santa Monica Boulevard in West Hollywood, the Los Angeles County Sheriff's Department said in a statement the following day.
