In two cases, a pair of robbers walked up to victims and snatched their cellphones before fleeing, according to a community alert from Chicago police. In one incident, the offenders robbed the victims at gunpoint.

All three robberies happened in the afternoon and evening hours, July 14 and 21, in the 1500 block of North Sedgwick Street near the Sedgwick Brown Line stop, police said.
