A corruption investigation has led to the arrests of some Romulus police officers, a former police official and his wife.
The Wayne County prosecutor's office says charges will be announced Tuesday.
WDIV-TV and WXYZ-TV report that arrests were made Monday.
Michigan State Police and the FBI have been investigating the police department for months. A search was conducted earlier this year at police headquarters, about 17 miles southwest of Detroit.
The Garden City home of then-police Chief Michael St. Andre and a tanning salon in Westland also were searched.
St. Andre cited a relative's health issues and offered his resignation earlier this month. It was to become effective Tuesday.
Romulus Mayor Alan Lambert has said the investigation stemmed from allegations secretaries in the department were paid with forfeiture money.
