Authorities say a former Georgia Tech graduate student was charged with stabbing a university researcher with a sword.

Georgia Tech spokesman Matt Nagel says the victim was taken to Grady Hospital in stable condition after the Thursday afternoon attack inside a building on campus. The victim's name was not released pending notification of family.

Police say Kshitij Shrotri is being held in the Fulton County Jail on an aggravated assault charge.

Nagel said Georgia Tech police officer Robert J. Turner of Griffin was injured slightly during the scuffle. He is in stable condition.

University officials say Shrotri received his Ph.D. in aerospace engineering from Georgia Tech in 2008.
