Police in Salford are investigating a hate crime where racist graffiti was spray-painted across the front door of a father and son's home.
Jackson Yamba shared a photo of the front door of his flat on Twitter on Saturday evening, which had been painted with the words "no blacks".
"How do I assure my traumatised 10-year-old that he is safe in his home?" Mr Yamba wrote alongside the image.
Mr Yamba said the crime had been reported more than a week ago, but Greater Manchester Police (GMP) had not yet visited to investigate.
However, after his post went viral online chief constable Ian Hopkins got in touch to say he had only just become aware of the "appalling crime" and apologised for the lack of response.
GMP later said it was aware of concerns about its response to the reports of racist graffiti at the flat in Irlams o' th' Height, north east Salford.
The force added that it was sorry Mr Yamba had "received a service below what we would seek to provide" and that they had visited him on Sunday morning.
A GoFundMe page has been set up to help the pair replace their front door, which exceeded its £1,000 target in less than six hours.
The father and son were also invited to be special guests at a local rugby match and meet the Salford Red Devils following the incident.
In response to the support he received, Mr Yamba tweeted: "I am really grateful for the amount of support across the country.
"There is no word to describe my gratefulness. My son and I want to thank you all."
Anyone with information should contact police on 101.
