GRAND FORKS, N.D. -

Grand Forks authorities say that there are currently no leads into who or what caused three suspicious fires over the weekend.

Police and Fire Departments were called to the 200 and 300 blocks of North 6th Street at 3 a.m. on Sunday morning.

The fires lit up debris and dumpsters in different alleyways as well as a single family home.

Neighbors noticed the fire and banged on the front door to make sure everyone got out.

No one was hurt.

"Based on the proximity to one another and close time frame that they all occurred in, we're kind of assuming that they're all related," says Lt. Brett Johnson.

There is still no report on the extent of the damage to the house.

If you have any information regarding the fires, contact Grand Forks Police.
