Donovan Middle School in Uica is currently under a lockout.

Utica School District Superintendent Bruce Karam says the lockout is due to a credible threat of violence that was made over the phone.

Utica Police are investigating the threat.

A lockout is used to secure buildings due to a threat outside of the building.

Students are expected to be released at their normal time.
