Officials say a man with a machete injured two people during an attack in a wooded area of the University of Arkansas campus.

University spokesman Steve Voorhies says the attack happened around 7:15 Thursday night. He says no one involved is believed to be a student and campus operations weren't affected. One of the victims was in critical condition.

University police Capt. Matt Mills says the suspect was also injured in the incident. He was taken to a hospital and has since been arrested.

Mills said police were collecting evidence at the scene and conducting interviews at the hospital late Thursday. He says it isn't immediately clear what prompted the attack. No identities were released.

Voorhies says the attack happened in the same area as a homicide earlier this year.
