A 54-year-old man has been arrested on suspicion of racially aggravated criminal damage after “no blacks” was written on a door.
Superintendent Howard Millington of GMP’s Salford Division said: “While we have a man in custody, our enquiries into this deplorable crime are very much ongoing.
“I want to emphasise that we are acutely aware of the strength of public feeling surrounding this incident.
"Both CID and neighbourhood officers are looking into this crime and we are working closely with our partners to support the victim, as is the case in all hate crimes.
"Let me reassure people that where incidents of this nature take place, we will always pursue a prosecution.
“If you have information which could assist the police with our investigation, please contact us as soon as you can.”

The graffiti was left on the door of solicitor Jackson Yamba and the entrance to the flats where he lives with his son, David, 10, in Salford, on 8 February.
Mr Yamba received public support after posting a photo of the graffiti on twitter, adding that the police had not visited a week after the message had been reported.
He added that the graffiti had left his son “traumatised”.
Since that initial tweet, Mr Yamba has said that he has received “ongoing and unlimited support” from his followers.
A GoFundMe page that was set up to pay for a new door for Mr Yamba has also quickly passed its £1,000 target.
Writing on twitter, Mr Yamba said: “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. I have been seen by the Police and received unlimited support from you all. We love you all.”
