Police Sgt. William Palmer said that the gun was found in a locked locker in an employee area for personal items at Seward Montessori School in Minneapolis.
The female employee, described by school authorities as an education assistant, reportedly had a concealed weapon permit, but such permits do not allow for the weapon on school premises.
The St. Paul Pioneer Press also reported on Tuesday that applications to carry a concealed weapon soared at the Anoka County sheriff's office on Monday. The office received 36 application for permits on Monday; on a typical day, the office will receive between 10 and 15.
The newspaper reported a similar spike in Minnesota's Dakota County. "What's different from this Monday to last Monday or the one before? Clearly the issue of the whole massacre in Newtown is the one difference," Dakota County Sheriff Dave Bellows told the Pioneer Press.
On Friday, a shooter identified as 20-year-old Adam Lanza entered Sandy Hook Elementary School in Newtown, Connecticut and shot 20 children, six staff members and himself.
Update: Police released a written statement to MinnPost, saying, "Minneapolis Public Schools (MPS) this morning worked with the Minneapolis Police Department (MPD) to apprehend a staff member ... There was no evidence that the employee intended to use the weapon; however, bringing a gun to school is against Minnesota law, violates MPS policy and creates a potentially unsafe situation."
