ELIZABETH CITY, N.C. (WVEC) -- At least 14 people were hurt in an attempted prison escape from Pasquotank Correctional Institution.

The fires were put out just before 5:30 p.m. but the correctional institution remains under lockdown.

Peter Sengenberger with Sentara Healthcare said that nine people were taken to Sentara Albemarle Medical Center. Two of those people were transferred to Sentara Norfolk General Hospital, and five more patients are expected to arrive. There was no immediate word on their conditions. Sentara asked that family of the injured avoid both campuses.

Students were dismissed, but those who ride the bus were required to have a parent at home when the bus arrived. If they did not, the bus driver took them back to the school.

After school events and athletics at all three schools were cancelled.
