2009: In the early morning hours on the day of the Grammy Awards, R&B singer Chris Brown is arrested and held on suspicion of making criminal threats on his girlfriend, fellow singer Rihanna, who suffered visible injuries and identified him as her attacker. The incident led Rihanna to postpone concerts scheduled in Indonesia and in Malaysia. Brown would plead guilty to felony assault in June and be sentenced to five years probation and six months of community service. The two singers are seen here in December 2008.
