As a result, Riverside Middle School was placed on lockdown for a short time as a precaution, then City Middle High School.
Though the credit union is located on Plainfield Avenue just south of City High School, the search for the suspect was focused for a time in the neighborhood west of the Cheshire business district.
Officers also canvassed the neighborhood behind the credit union.
The robbery occurred sometime after 9 a.m. on October 31. Two suspects have been caught and are in police custody.
