NEW HAVEN, Mich. — A federal investigation of corruption in suburban Detroit has reached a fourth community in Macomb County.

Christopher Craigmiles, a trustee in New Haven, and Brett Harris, a former trustee, were charged Thursday with taking bribes from an undercover FBI agent. The government says Harris’ alleged crimes occurred before he was defeated for re-election in November.

The charges against Harris were filed as a criminal information, which means a guilty plea is likely. His attorney declined to comment. Craigmiles couldn’t be immediately reached for comment.

Separately, three officials in three townships in Macomb County were charged last year.

A trash hauler formerly known as Rizzo Environmental Services has been cooperating with investigators. Rizzo has new ownership and the name is being dropped from trucks and the business.
