Police are treating the scrawling of graffiti on a house in Westland Road as a hate crime.
The words ‘get out or be put out’ and ‘Brits only’ were daubed on the wall over the weekend.
A police spokesman said, “No one has the right to decree where someone should live based on their race, or religion – this is HATE crime!
“The neighbourhood you live in is just that – a neighbourhood with a mix of people from all walks of life and it is up to each one of you to make it a community. To make it a safe place where you can move around freely and go about your daily business without fear of crime.
“There is no place for hate crime in our communities in Portadown. If you are unhappy with the actions of others in your neighbourhood there are legitimate steps you can take – you can report crime to us, you can report housing problems to the appropriate housing association, you can work with your community to find solutions together.
We are asking anyone with information about this criminal damage to contact us on 101.
Help us to fight hate crime and keep your community safe.”
