ABERDEEN - The principal who told middle school students they were in a "no hugging school" has resigned.

Tyler Blackmore filed his resignation from Matawan-Aberdeen Middle School on April 5. He had worked there since July 2010. Several sources tell News 12 New Jersey Blackmore is being forced out.

The school board president says the resignation was a personnel matter and the reasons were confidential.

Blackmore caused uproar in March when he told his more than 900 students that they were in a "no hugging school" because of some "incidents of unsuitable, physical interactions."

Matawan-Aberdeen isn't the only school to institute a no hugging policy. Several principals nationwide have done so and believe the embrace can lead to a disruption in learning and even students bullying others.
