Montgomery County Police on Monday ramped up their presence at county elementary schools, though they emphasized no threats had been made to schools in the county.

The department said its presence at the schools (officers were detailed to schools for students’ arrival this morning and will be again for dismissal this afternoon) was primarily to “provide a presence and reassurance to the community,” according to a press release.

On Friday, gunman Adam Lanza killed 20 first-graders and six staff members at Sandy Hook Elementary School in Newtown, Conn.

School staff at Wood Acres Elementary School (5800 Cromwell Dr.) this morning reported a “suspicious message” left on the school’s answering machine. The officer on detail at the school responded.

Police say they will discuss plans for the rest of the week with Montgomery County Public Schools officials.
