Brown has not commented on the allegation

Frank Ocean says he won't pursue criminal charges against Chris Brown, who is alleged to have punched Ocean in a recent fight.

"As a child I thought if someone jumped me it would result in me murdering or mutilating a man," the R&B star wrote on his Tumblr page Saturday. "But as a man I am not a killer. I'm an artist and a modern person. I'll choose sanity. No criminal charges. No civil lawsuit."

Brown remained under investigation for his role in a fight outside a West Hollywood recording studio on Jan. 27, Los Angeles County Sheriff's spokesman Steve Whitmore said.

Witnesses told deputies that Brown punched Ocean during an argument over a parking space. Ocean later tweeted that he "got jumped by Chris and a couple guys" and suffered a finger cut.

Brown has not commented on the allegation.

Whitmore said Ocean had said he "desired prosecution." He said the investigation was continuing because Ocean has not told authorities that he's had a change of heart.

"It's ongoing until an official statement is made to us," Whitmore said.
