DETROIT (AP) A man has been charged with conspiring to bribe city officials in the awarding of a Detroit sludge-recycling contract.

No city officials are identified in the criminal charge against Jim Rosendall that was unsealed Monday.

Rosendall is a Grand Rapids-area man who represented Synagro Technologies, a Houston company that recycles waste from treatment plants. The Detroit City Council awarded a contract to Synagro in 2007, but there are questions about how it got the deal.

The charge alleges an intermediary made payments to a city council member in exchange for a vote in favor of the Synagro contract. The government alleges Rosendall tried to influence city officials by jetting them to Las Vegas and providing other gifts.

Rosendall has been cooperating with the FBI in its investigation.
