Police searching for a missing three-year-old boy said they are "deeply concerned" as they made a fresh appeal for help in finding him.
Mikaeel Kular disappeared from his home in Edinburgh after being put to bed on Wednesday night and hasn't been seen since.
A major ground, air and sea search has so far failed to find any sign of him.
Police Scotland superintendent Liz McAinsh said: "We are obviously deeply concerned that we have had no sightings of Mikaeel. All lines of inquiry in the investigation remain open, we are pursuing many lines of inquiry.
"I would ask anyone who has got any information to get in touch with us.
"We still have no evidence of any criminality at this point."
Family members were joined by neighbours and emergency services as they searched through the night for him as temperatures plunged to just above freezing.
