Police today released pictures of the two teenage friends who have been missing from home for nearly three days.
Corrina Stirland, 15, and 14-year-old Rebecca Armer were reported missing on Wednesday in Scunthorpe.
Humberside Police said their disappearance was out of character and they were concerned for their welfare.
The force said it had received reports from the public of an unconfirmed sighting of the girls at 6am today on Gainsborough Road, Kirton Lindsey.
The last confirmed sighting was by a friend at around 9.35pm on Thursday in the Cole Street area of Scunthorpe.

She was last seen wearing a black coloured top, leggings, a belt and black coloured Ugg style boots.
