Rumors quickly spread Monday morning through Facebook and Twitter that Commack High School was on lockdown, but school personnel say those reports were false.
More then 100 tweets, mainly from high school students, went out just before 10 a.m. stating that the building was under severe security. However, those speculations were unfounded, district officials said. A number of those comments were regarding rumors about a gun being in the building.
A student was later arrested for having an airsoft pellet gun in his locker.
"The high school is not on lockdown," Brenda Lentsch, spokesperson for the district confirmed.
"We're working on getting the facts together, but all is safe and secure, no cause for alarm," Lentsch said.
