Canceling his scheduled performance at the 51st annual Grammy Awards after becoming the target of the Los Angeles Police Department (LAPD)'s investigation for felony battery, Chris Brown has turned himself in to the authorities on late Sunday, February 8, to be questioned in relation to the case. Per Los Angeles Time as being informed by the LAPD, Chris voluntarily showed up at the Wilshire Police Station at about 7:15 P.M., accompanied by his attorney Mark Geragos and Geragos' investigator, Scott Ross. They entered the building through a back door.

Chris reportedly has been booked on suspicion of making criminal threats, but was released after posting $50,000 bail. The case will now be sent to the district attorney's office and further charges could be filed, E! News claimed in a report on its site. He is due to back in court on March 5.

Earlier Sunday, LAPD confirmed to have conducted an investigation with Chris Brown as the suspect after an unidentified female made a 911 call and claimed that the R 'n' B performer attacked her. The incident reportedly stemmed from a heated argument, taking inside a car in L.A.'s Hancock Park neighborhood at around 12:30 A.M.

"The identity of the victim will not be released," Officer April Harding previously said in a statement. "Any victim who's involved in a domestic violence incident is entitled to confidentiality." Officer Harding then added, "If police locate Brown, yes, he's subject to arrest." At time of writing, there has yet word on the identity of the female victim. Nevertheless, speculation is mounting that the victim is Chris' girlfriend, Rihanna, as she has canceled her performance at the Grammys.

No comment has been made by either Chris' or Rihanna's camp regarding the case.
