MONROE, Conn. — A Connecticut man has been arrested on harassment charges alleging that he placed calls to Newtown schools claiming that the 2012 massacre at Sandy Hook Elementary School was fabricated.

Thirty-year-old Timothy Rogalski of Wallingford was arrested Tuesday after police traced the calls to his home.

He is charged with harassment and disorderly conduct and is being held on $2,500 bond. The Associated Press could not immediately determine whether he has an attorney.

A gunman killed 20 children and six adults at the elementary school on Dec. 14, 2012, before committing suicide.

Police say Rogalski placed disturbing phone calls to schools including Sandy Hook Elementary, which is operating temporarily in the neighboring town of Monroe as a new school is built to replace the one demolished after the shooting.
