Flint water crisis: FBI joins investigation

Other agencies involved in investigation include U.S. Attorney's Office, EPA

FLINT, Mich. – Federal prosecutors say the FBI is working with a multi-agency team investigating the lead contamination of Flint's drinking water.

The U.S. Attorney's Office in Detroit on Tuesday morning issued the following statement:

"The U.S. Attorney's Office is working with a multi-agency investigation team on the Flint water contamination matter, including the FBI, the U.S. Postal Inspection Service, EPA's Office of Inspector General (an independent office within EPA that performs audits, evaluations, and investigations of EPA and its contractors to prevent and detect fraud, waste, and abuse) and EPA's Criminal Investigation Division (which investigates potential criminal violations of federal environmental law)."

The U.S. attorney's office said in January it was investigating the water crisis with the EPA.

Officials haven't said whether criminal or civil charges might follow.

Flint switched its water source from Detroit's water system to the Flint River in 2014 to save money while under state financial management. The river water was not treated properly and lead from pipes leached into Flint homes. The city returned to Detroit's system in October while it awaits the completion of a separate pipeline to Lake Huron this summer.
