The chief of Frederick police will become chief of the U.S. Capitol Police, authorities said Wednesday.

Kim C. Dine, a former Metropolitan Police Department assistant chief and Mamaroneck, N.Y., native who took over Frederick’s police department in July 2002, is to move to the Capitol Police in early December, according to an announcement from the city of Frederick.

Phillip D. Morse retired as chief of the Capitol Police in the summer after 28 years with the department. Assistant Chief Thomas P. Reynolds has been running the department, which oversees security at congressional facilities, on an interim basis.
