Denmarks capital was thrown into chaos in August after more than 40 vehicles were torched. A 21-year-old man was arrested in connection to the fires and he remains in custody, a police spokesman confirmed.
However express.co.uk has now uncovered more arsonists are on the lose.
The Copenhagen police spokesman said despite the suspect being detained after the first batch of fires, the blazes have continued to plague the city.
The last car fire happened just five days ago.
A local resident, who asked not to be named, said she was concerned about the attacks.
The woman added that the fires had started in areas where many second-generation migrants live.
Police are still hunting for suspects but the spokesman added there had been fewer incidents after the force increased their presence in the streets.
The spokesman also declined to comment on whether the arsonist attacks were connected to the out-of-control car fires hitting Malmö in south Sweden.
But in August police spokesman Rasmus Bernt Skovsgaard said: It is still too early to say anything on the extent to which this could have a connection to the fires that have happened in Sweden.
