A Californian man was arrested yesterday (14SEP06) in Los Angeles on suspicion of impersonating a US federal agent in a bid to land a job as Brad Pitt and Angelina Jolie's security consultant. NELSON MERCADO has been indicted for falsely claiming to be a special agent for the US Department of Homeland Security when he made a job application to Sunset Protective Services and Investigations. The 46-year-old sought employment with Sunset with the sole intention of providing the Mr And Mrs Smith stars with security services, according to US Attorney's spokesman Thom Mrozek.
