Residents lay message and toys on the Ferry Gait Crescent in Edinburgh, near the home of Mikaeel, after a child's body was discovered in Kirkcaldy.
Floral tributes and soft toys have been placed near Mikaeel's Edinburgh home.
A steady stream of people, including many local residents with children, have been arriving throughout the day to pay their respects.
The tributes are being left at a small park in the Drylaw area, round the corner from the three-year-old's home.
People have also been lighting candles at the scene.
One tribute message said: "God bless you. Rest in peace, sweet little angel."
Another read: "RIP Mikaeel Kular. May the angels hold you tight."
At the scene, grandmother Leann Bruce said: "I live in the neighbourhood. It's been quite upsetting really, to be honest, and I just wanted to come and pay my respects."
She said she did not know Mikaeel but had seen him many times when she was out walking her dogs.
"He was always smiling and waving, but I didn't know him personally," she said.
On the community response, she said: "They've come together really well, it's been nice to see. I feel like everyone's upset by this and was hoping for a good outcome, but sadly it's not been, so it's quite distressing.
"I came down because you've got to give a thought to the other children that are affected by this. They must be feeling so sad and devastated. I just feel so upset by it."
Denise Ormsby, 52, said : "I just think it's just so sad. I just wanted to pay my respects. It's wonderful the way everybody (in the community's) come out."
Trevor Wright, 63, said: "I just wanted to pay my respects to the young lad. It's very sad."
