Two men have been arrested in connection with a series of race hate attacks in east Belfast.
Homes and cars were damaged and graffiti daubed on walls in east Belfast in a spate of linked hate crimes against Romanians and Slovakians, police said.
Two men - aged 20 and 22 - have been arrested in connection with offences.
Investigators said it was too early to say which group was responsible for the trouble on Monday - which included six attacks - but have not ruled out loyalist paramilitary involvement.
Superintendent Mark McEwan said: "These incidents which took place last night were designed to intimidate families within those homes."
A large rise in racist incidents has been recorded across Belfast since a PSNI operation targeting perpetrators began in May.
