Plainfield's fire chief has stepped down after accusations surfaced that his son sexually assaulted a teenage cadet.
Ralph Wells made the announcement on Wednesday after a meeting, according to officials.
However, he has not excused himself from the company.
Deputy Chief Larry Loomis was appointed as the interim chief.
Kevin Wells, 27, a fire captain, was arrested late last month and charged with sexually assaulting a 17-year-old junior member.
The investigation remains active.
