Worcester Police Chief Steven Sargent is retiring after 37 years with the department, the last seven of which he served as chief, the city announced Friday.

Sargent began his career in Worcester in 1986 as a patrol officer. He served in several divisions within the department, including the detective bureau and gang unit. He was promoted to deputy chief in 2007 before assuming the role of police chief in May 2016.

According to a report from the Worcester Telegram & Gazette on Aug. 17, Worcester Officer Robert J. Belsito is threatening to sue the city over alleged harassment he received from Sargent, including a road rage incident in April.

Sargent’s retirement also comes amid a Justice Department investigation into the Worcester Police Department that was launched in November. The investigation is looking into whether the WPD has a pattern or practice of excessive force or engages in discriminatory policing based on race or sex.

Deputy Chief Paul Saucier has been appointed interim police chief, effective immediately, the city announced Friday evening.
