One arrest has been made, and more are expected, in a weekend shooting that left three people hurting.  Shreveport police have arrested 19-year-old Kristopher McClain on a charge of being a principal to aggravated battery. Detectives say they've been able to gather enough evidence to link McClain to a shooting that happened in the 2300 block of Milam in which three other teens were hurt. Police say two groups of young people were exchanging words when somebody started shooting. A 15-year-old and a 19-year-old were both hit by bullet fragments. They were treated for minor injuries and released. Another 19-year-old was shot in the leg. He's still in the hospital, but is expected to recover.
