Ethnic minorities in the South Belfast area have been warned that racist groups may be planning violence in the area this weekend.
They have been urged to be vigilant by police who said they have received intelligence on possible disturbances.
Police patrols have been increased in the area, which has the highest proportion of ethnic minority families in Northern Ireland.
Inspector John McCracken said the community should not panic.
"This message is not meant to alarm people. It is simply a proportionate response by police in response to ongoing problems with-race hate crime in the south Belfast area."
There have been around 90 race-related incidents in south Belfast since the beginning of the year.
