Gun scare at the University of Jyväskylä

I just received this email from the University of Jyväskylä:

University buildings on Mattilanniemi campus cleared for security reasons

University’s Mattilanniemi campus buildings MaA, MaB, MaC and MaD are cleared and staff and students are requested to leave the premises immediately, because the police investigating a gun scare in the buildings. The police asks people to leave all doors to offices and classrooms open and unlocked, so that the buildings can be checked quickly. Staff and students can leave campus for today. The buildings will be open normally on Friday unless otherwise notified.

Information is currently a bit sketchy; Keskisuomalainen and Helsingin Sanomat are both currently following this story online.  The whole picture should be clear later today or tomorrow.
