BOSTON (1/15/10)--The Massachusetts Bank Robbery Task Force asked the Massachusetts Credit Union League to alert credit unions about a series of credit union and bank robberies perpetrated by a single individual in the greater Boston area since Oct. 29. The task force comprises elements of the Massachusetts State Police, Boston Police and police forces in surrounding cities, said the league (e-Weekly Jan. 13). During the past two months, nearly 20 robberies were perpetrated by the individual. On Jan. 8, he robbed a credit union in Cambridge. The league was told that a disproportionate number of the institutions robbed by the individual have been credit unions. The task force believes he may be targeting credit unions. The league sent the notice to its entire membership statewide. To date, the robber's activities appear to be limited to the area in and around greater Boston.
