Town residents turned over a total of 80 firearms, including pistols, shotguns, rifles, and two assault rifles, during a gun buy-back led by local churches and police last weekend. “This is an excellent example of what we can accomplish when members of the community and law enforcement partner together in an effort to solve complex problems,” Police Chief Fred Ryan stated in an announcement issued Tuesday. The collection event, held in the Department of Public Works yard on Grove Street, was organized by Park Avenue Congregational Church, Calvary Church, Trinity Baptist Church, and First Parish of Arlington, with assistance from local police and the Middlesex County Sheriff’s Office. Participants were given gift cards donated by local businesses in exchange for their firearms and ammunition, which will be disposed of by police. Any residents who would like information about turning in firearms or ammunition may contact Police Captain Juliann Flaherty at 781-316-3942 or by e-mail at firstname.lastname@example.org.
