LOS ANGELES (ES): - Chris Brown has received death threats. The R&B singer's lawyer Mark Geragos has asked the Los Angeles Police Department to investigate several anonymous calls made to his office, which he believes could pose a serious danger to the singer's safety. TMZ claims Mark immediately reported the threats to the LAPD, who are currently investigating the matter. It is not yet known what specific comments were made. Mark represented the 'With You' singer during his own police ordeal in 2009, when he was arrested for assaulting his on-off girlfriend Rihanna.
