Police in Ferguson, Missouri, fired tear gas and rubber bullets at crowds of protesters late Monday, marking a second night of clashes in response to the fatal shooting of an unarmed teenager. At around 8 p.m. local time, protesters gathered near the QuikTrip convenience store in Ferguson that was looted and burned Sunday night following the death of Michael Brown, an 18-year-old who was shot and killed by a police officer over the weekend. Brown was unarmed and reportedly had his hands up at the time of the shooting. Police in riot gear with the support of SWAT vehicles used tear gas and “beanbag rounds” after protesters reportedly threw rocks at police, according to Ferguson Police Chief Tom Jackson. St. Louis County Police spokesman Brian Schellman said at least five people were arrested, but there was no looting. The FBI announced Monday it would open a parallel investigation into Brown’s death. Attorney General Eric Holder said in a statement, “At every step, we will work with the local investigators, who should be prepared to complete a thorough, fair investigation in their own right.”
