Burglars stole an unknown amount of cash from two safes in first floor offices of the University of Hawaii-Manoa’s athletics complex over the weekend, UH campus security and Honolulu police said Monday.

UH public information officers declined to identify the exact location of the safes, or how much was taken. It’s also unclear when the burglaries occurred.

UH Athletics Department employees discovered the break-ins when they arrived for work Monday morning, campus security chief Wayne Ogino said.

Honolulu Police Department officers were called to investigate the incident.
