SEFFNER, Fla. — Hillsborough County investigators are looking into reports of a possible weapon at a high school in Seffner.

Armwood High School was placed on a lockout Monday afternoon, according to Tanya Arja, the Hillsborough County Schools chief of communications.

The school was earlier on a lockdown because of the possible weapon.

A lockout means nobody is allowed to get into the school or to leave until an all clear is given.

We'll post more details as they become available.
