Chris Brown tackles critics in online outburst

Chris Brown has posted an angry rant online urging his critics to back off following his bust-up with fellow R&B star Frank Ocean and allegations he faked his community service sessions.

The Kiss Kiss hitmaker hit the headlines again last month after he was embroiled in an altercation with the singer over a car parking space outside a Los Angeles recording studio.

A police report obtained by TMZ.com earlier this week contained an allegation that Brown threatened to shoot Ocean, who was allegedly left nursing cuts to his head and hand, which required medical attention.

Brown is also facing accusations his mother signed off hours at the children's centre in Richmond, Virginia where she was a director, to help fill the community service quota her son was ordered to complete as part of his conviction for assaulting Rihanna in 2009.

On Tuesday, the scandal-hit star took to his Instagram account to hit back at his critics.

He writes, "Im wise I can handle the hate but enough is enough yo!!... Im a human being and I honestly think I deserve respect. Im sick of being accused. Im tired yall (you all) just dont understand Ive been going through this s**t since I was 19 years old... you cant sit here and tell me to calm down, when am I gonna get a positive outcome out of anything I do?

"Just when everything seems to be going good, some new s**t happens. A day in my shoes is a day in hell, believe it or not!"

Brown's lawyer Mark Geragos has also hit back at the Los Angeles District Attorney's allegation that Brown submitted bogus community service records, branding it "scurrilous, libellous and defamatory".
