GREELEY, Colo. (AP) -- Police have arrested two Greeley men who were found with four young girls who had been reported missing.

KMGH-TV in Denver says the girls, ages 12, 10, 6 and 5, were reported missing Sunday evening. The two older girls were babysitting the younger girls when they headed from one apartment to another in the same complex. They were reported missing when they failed to arrive.

Police found all four girls about 3 a.m. Monday with the two men in an apartment about a mile away.

Police Sgt. Susan West tells KMGH there appears to have been sexual activity between one of the men and one of the older girls. The girls have been returned to their families.
