Police are investigating a possible link to loyalist paramilitaries following a spate of racist attacks in east Belfast.
Three vehicles were set on fire in what police described as racially motivated hate crimes in the early hours of Sunday in the Florida Street, Wayland Street and Carlingford Street areas.
All vehicles were extensively damaged. In one incident the fire on the vehicle resulted in a number of other nearby cars damaged.
Speaking to the BBC, police said there was a link to the incidents and did not rule out paramilitary involvement.
"Given the time and location we are definitely saying there is a linkage between the incidents. At this stage we are not ruling out any paramilitary involvement. The investigation is very much open at this time," Superintendent Robert Murdy said.
Police have appealed for witnesses, or anyone with information to contact police.
A statement said: "At this stage, all lines of enquiry are being kept open. We would encourage anyone with any information about these incidents, to contact us on the non-emergency number 101, quoting reference 362 22/10/17. Or, alternatively if someone would prefer to provide information without giving their details they can contact the independent charity Crimestoppers and speak to them anonymously on 0800 555 111."
