In a statement issued last week, the council said it was helping the police with an investigation into alleged financial irregularities.
Two offices, the economic development service's headquarters in Chester Business Park, and Hadfield House, where the education advisory service is based, were closed during the raid, affecting about 90 council employees.
The county has not named the people suspended. Tom Stephenson, head of public affairs, said: 'I must stress the suspensions are because of investigations which are still continuing. We cannot say yet whether any disciplinary action will be taken.'
The council became concerned following an internal auditor's report and called in the police.
