HOUSTON -

Four houses on a north Houston street caught fire Friday, and investigators said juveniles may have started all of them.

The fire started inside one family's home, then spread to homes in the 5300 block of Terry near Griffin at about 3:30 p.m. Friday.

About 60 Houston firefighters battled the flames and put out all the fires by 4 p.m.

All of the homes sustained major damage, firefighters said. A shed was destroyed by fire, officials said.

Neighbors said they couldn't believe what they saw.

"When I stepped out of my house, I saw all the fire trucks out here. All these houses on fire and this white truck pulling up," said Angela Beal, who lives nearby.

The white truck belonged to the Leonard family. Investigators said their home is where the fire started. They family temporarily lost custody of their six children in 2011 after it was discovered they were living in an air-conditioned storage shed. Through generous donations, they were reunited and able to move into a home on Terry Street.

"We have our own room, so we don't have to be squished or anything," said Saleem Leonard.

The family now has to find another place to live until their home can be repaired.

No injuries were reported.

Neighbors said they saw several juveniles running out of the homes at about the time the fires happened. Arson investigators said they are interviewing those juveniles.

Investigators said they are trying to determine the cause of the fires.
