GREENVILLE, PITT COUNTY -

Police said an early-morning apartment fire in Greenville that displaced two families has been ruled suspicious.

The fire Thursday morning caused major damage to several apartment units at 3214 Summer Place, Greenville Police said. It started in apartment 5 and spread upstairs to apartment 10, said investigators.

Firefighters on scene extinguished the blaze at about 3:25 a.m. Thursday.

Some residents were allowed to return to their apartments later Thursday morning. Dionne Joyner lives on the second floor of the apartment building and said she was asleep when the fire started.

She was awoken by Ali Hopkins, a man visiting a neighbor across the street who heard fire detectors going off.

"You could smell the smoke and that's when I started beating the doors trying to get it open," said Hopkins.

Joyner said she is grateful that Hopkins came over to warn her.

"Everybody was sleep, me and my neighbors, so if it wasn't for this angel, we would of all been gone," said Joyner.

Three apartment units were damaged in the fire, said officials. The two families who are displaced are being helped by the Red Cross.

Greenville Fire/Rescue ruled the fire suspicious and has called out its fire investigator.

Greenville Police are continuing to investigate. At last check, no arrest had been made.
