New video released by police shows a Minnesota hospital patient attacking nurses with a metal rod.

Charles Emmett Logan, 68, can be seen on the hospital's surveillance system wildly swinging the bar as nurses frantically try to get away.

The footage ends with him clearly striking one woman as he goes out a door.

Police said Logan was involved in a dispute with family members before last weekend's attack, but it's unclear if that is what triggered the violence.

Logan then left the hospital and was tackled by police after a Taser failed to subdue him. After being handcuffed, Logan lost consciousness and died after being rushed back to the hospital.

The cause of death is not yet known. 

One nurse reportedly suffered a collapsed lung, another broke her wrist, and two others sustained cuts and bruises.

Here's more from the St. Paul Pioneer Press:

The Minnesota Nurses Association, which represents the injured workers, released the following statement about the incident:

"The hearts of Minnesota nurses go out to the families of the patient and the nurses who they hope will begin to heal from this tragedy.

Once again, nurses showed their dedication by responding to the emergency situation to help all the health care workers injured in the attack. Sadly, this incident is another act of patient on nurse violence that nurses and health care workers face every day. Only their training, education and courage prevented this sad situation from becoming worse."

The violent behavior was reportedly extremely abnormal for Logan, a father and veteran mechanic for Metro Transit who had been admitted to the hospital after suffering recent bouts of confusion and delusions.

He had been involved in a dispute with some members of his extended family before the outburst, but it's unclear what effect, if any, that had on the attack, Maplewood Police Chief Paul Schnell said.

"This was very out of character. ... We're talking about like a salt-of-the-earth kind of guy," Schnell said.

"Virtually every element of this is tragic," Schnell said. "Certainly for the man himself, and we still don't really know what happened to him. Second, for his family, obviously, he was someone's dad, brother, uncle, cousin and then, of course, for the nursing staff who were just going about doing their work. ... Folks knew he was struggling, but I don't think anyone expected this would end in violence."

He added that attacks on medical staff are rare.

The hospital, which is part of HealthEast Care System, declined to answer questions about the incident.
