Peter Walls, chief executive of Sunderland Housing Group, said: "As far as we are concerned, Peter has some issues with his former employers and is trying to help their inquiries. He has chosen to go away and sort those out. Peter has got a lot on his plate."
Sunderland Housing Group took over the city's 38,000 houses after a stock transfer in 2001. Spoors was an important part of the team because of his experience in housing in the North-east. He had been a regional director for the North-east of Miller Homes.
Walls said that the group was considering how to restructure in the wake of Spoors' departure. He said: "The work he was doing here was good, but luckily we have got quite a good team. We will either look internally or to the marketplace [for a replacement]."
The police investigation surrounds financial irregularities that are alleged to have occurred between October 1997 and January 2002. The figure in dispute is more than £300,000.
