MIDDLEBORO — Middleboro Police Chief Joseph Perkins will retire within the next 30 to 60 days, he announced in a letter read at the Sept. 9 Select Board meeting.

He made the announcement, the letter stated, with “bittersweet sorrow and joy.’’

Select Board Chair Mark Germain, who read the letter, described the chief as “someone I admire and respect.’’ He said he wished the chief “well in his retirement.’’

No information was immediately available on plans for a successor for Perkins.
