A police dispatcher in Virginia said a man with a long knife stabbed three people inside a plasma donation center as nurses and patients hid inside a bathroom.
The dispatcher warned officers that witnesses said the man was attacking people with a machete Thursday in the Octapharma Plasma center in Petersburg, Virginia.
A first responder could be heard saying that one of the victims lost a finger.
Hospital officials said Thursday that one male was in critical condition, a female was in fair condition and a female was in good condition.
Irene Banks told WWBT that police praised her daughter, a manager there, for stopping the attacker before officers arrested him.
A Virginia prosecutor said the man could be charged at a minimum with malicious wounding.
