Five people were shot and wounded near a San Jose nightclub early Sunday where controversial R&B singer Chris brown was making an appearance, authorities said. The shooting happened near the Fiesta nightclub on Monterey Street and Rancho Drive about 1:20 a.m. Paramedics took four victims, most of whom were shot in the arms or legs, to area hospitals. A fifth victim showed up at a hospital. The victims, whose names weren’t released, were expected to survive. Police reportedly detained several people in the case. Brown was at the nightclub for a “Capricorn Bash” birthday party that also featured from the KMEL radio station, according to online promotional materials. Videos posted online show Brown, 25, on stage when gunfire erupts, prompting security to whisk the singer to safety. Brown was not hurt and later posted a message on Twitter that read, “I’m 100.” The Grammy winner is preparing for a national tour beginning later this month that includes a concert March 6 at the SAP Center in San Jose. He has generated controversy as a result of a number of high-profile incidents, including his assault in 2009 of then girlfriend and pop star Rihanna.
