A new regulation at Virginia Tech bans concealed firearms and other weapons from university buildings and major events such as football games.
The school's Board of Governors approved the measure on Monday. The new regulation replaces an existing policy, and concerns firearms carried both by concealed permit holders and non-permit-holders.
Attorney General Ken Cuccinelli said in July that universities didn't have the authority to ban people from bringing guns into school facilities, as long as they have concealed carry permits. Those permitted under Virginia state law to own a firearm must be allowed to carry it openly, or concealed with a permit on the open grounds of public institutions, he said.
But in January, the Virginia Supreme Court ruled that public universities could ban open carrying of firearms in buildings and at events.
Virginia Tech officials said Monday that legal opinion had changed, and the regulation was approved without comment.
In 2007, the university was the site of the deadliest massacre by a single gunman in U.S. history. A student, Seung-Hui Cho, killed 32 people and then turned the gun on himself.
