NORTHAMPTON, Mass.—Two men are being held on charges they stole nearly $400 from a group of Girl Scouts selling cookies at a store in Massachusetts. An adult supervising the Scouts suffered a broken nose and arm injuries trying to stop the men.

Authorities say 22-year-old Nicholas Taverna of Greenfield and 25-year-old Cassidy Michalski of Deerfield were held on $5,000 bail each at their arraignment Tuesday on charges of unarmed robbery, assault and battery with a dangerous weapon and shoplifting.

Police say the suspects stole two cellphones from the Walmart in Northampton on Saturday and tried to trade them for drugs in Holyoke. When that failed, they returned to Northampton where they had seen the 11- and 12-year-old Scouts earlier, and stole their cash box.
