Police chased 15 to 20 youths around Nicollet Mall Friday when they simultaneously attacked a group of bikers, the Star Tribune reported.
They have been nicknamed "flash robs" because of their resemblance to "flash mobs", where people will simultaneously start dancing in a public place. The difference here is that instead of dancing, these youths are attacking then fleeing in bulk, KARE 11 reported.
There have been six similar incidents since February, usually centering around Nicollet Mall, KARE 11 reported. In Friday's incident, one man flew off his bike and broke his jaw while another was surrounded and beaten, the Minnesota Daily reported.
Four people from that Friday's attacks have been captured and charged: three juveniles, ages 15, 16, and 17, and Antonio D. Jones, 20, with felony fifth-degree drug possession, gross-misdemeanor third-degree riot, and misdemeanor fifth-degree assault, the Minnesota Daily reported.
