(CNN) At least 10 people have died after a blaze swept through an apartment block in central Paris in the middle of the night, a spokesman for the city's prosecutor told CNN Tuesday.

Paris prosecutor Rémy Heitz said earlier that the fire may have been started maliciously.

At least 37 people, including six firefighters, suffered injuries, fire service spokesman Clément Cognon said. One person was seriously injured.

Heitz said that one woman, who lived in the building, had been taken into custody, and an inquest has been opened. The 40-year-old woman was arrested in the road immediately after the fire, Heitz said. She has a history of psychological problems, he added.

Firefighters are still working to control the blaze on the top two floors of the eight-story building and searching for residents, Cognon told AFP, adding that the death toll could rise. He added later that there was a risk of collapse between the two upper floors.
