A political consultant facing trial in a Detroit City Council pay-to-play scandal has been arrested following a possible domestic dispute at his home.

Police spokesman John Roach tells The Detroit News and Detroit Free Press that Sam Riddle hasn't been charged, but was taken into custody Monday after officers responded to a domestic complaint.

Riddle had been living with girlfriend and ex-state Rep. Mary Waters. Both are awaiting trial on accusations of bribing a Southfield councilman.

Riddle also is charged with taking bribes for then-Detroit City Council member Monica Conyers to ensure her vote on a sludge contract. The wife of U.S. Rep. John Conyers pleaded guilty and will be sentenced March 10.

Riddle's trial is next month.
