The Patchogue-Medford School District, which closed the district's high school Monday after receiving a potential threat, announced classes would resume Tuesday.

"Suffolk Police determined that the threat was unfounded. Based on that conclusion, the high school will resume normal classes in person tomorrow, Tuesday, March 14," said Superintendent Donna Jones on the district's website.

Jones had said on the website Sunday the district received a message concerning a potential threat against the high school. Jones said the district informed Suffolk County Police, who opened an investigation, and “out of an abundance of caution” decided to close the campus on Monday.

All other schools in the district remained open, Jones said.

Suffolk police said Monday they were investigating the threat.
