Norfolk Fire-Rescue crews were sent to a structure fire at 1233 Westover Avenue at 6:35 p.m., and when the first unit arrived four minutes later, they found a fire on the second floor of the occupied residential apartment building, and a second alarm was called.

Firefighters found a person on the second floor and the person was taken to the hospital with serious injuries, Lenhart said.
