Indianapolis police are investigating the robbery and attempted robbery of two north-side Walgreens stores Tuesday morning. The first incident happened about 1:30 a.m. at the Walgreens at 86th Street and Ditch Road. The store manager told police two black men armed with guns entered the store, but became nervous and ran out 10 seconds later. Then, just after 4 a.m., the Walgreens at 86th Street and Michigan Road was robbed at gunpoint by a black male wearing a white ski mask. The suspect drove off in a blue-green car. Police say the two incidents are likely related. Fox59 will have more at 4 p.m.
