FLINT, Mich. (AP) — The Latest on criminal charges dropped in the Flint water scandal (all times local):

4:20 p.m.

Michigan Attorney General Dana Nessel says “justice delayed is not always justice denied.” But not everyone is pleased with her staff’s decision to drop criminal charges against eight people in the Flint water scandal while investigators keep digging.

Nessel says a “fearless” team still is on the beat. She issued a statement after the state solicitor general said the investigation would start anew with a cache of recently obtained records.

Flint activist Melissa Mays says she doesn’t have confidence that “victims will ever see justice.” She says her hopes have “definitely waned.”

Flint used water from the Flint River that wasn’t properly treated. The corrosive water unleashed lead, and bacteria were blamed for a Legionnaires’ disease outbreak.

Prosecutors plan a town hall-style meeting with Flint residents on June 28.

The lawyer for Michigan’s former health director says they feel “fantastic and vindicated” by the dismissal of charges in the Flint water scandal.

Chip Chamberlain acknowledged that Nick Lyon could be charged again as prosecutors start a new investigation. But Chamberlain says he’s confident the probe “will yield no evidence of any criminal wrongdoing.”

Lyon was head of the state health department until January. He was charged with involuntary manslaughter and accused of failing to timely inform the public about an outbreak of Legionnaires’ disease when Flint was using the Flint River in 2014 and 2015.

The water wasn’t properly treated to reduce corrosion and lead leached from old pipes as a result. Tests also revealed bacteria.

Michigan officials are ordering a Flint hospital to take steps to reduce the risk of exposure to Legionella bacteria and Legionnaires’ disease at the facility.

The Michigan Department of Health and Human Services and the Department of Licensing and Regulatory Affairs on Wednesday ordered McLaren Flint Hospital to “immediately correct conditions.”

Hospital spokeswoman Rosemary Plorin says in an email that the hospital believes the order “is unfounded and represents the state’s continuous efforts to shift blame for their bad decisions made five years ago onto our hospital.”

Flint, while under state financial management, switched to the Flint River for water in 2014 without treating it to reduce corrosion. Lead leached from pipes, contaminating the system. At the same time, a deadly Legionnaires’ disease outbreak occurred that led to criminal charges against government officials.

Legionnaires’ is a severe form of pneumonia caused by water-borne bacteria.
