A woman was detained on Tuesday as part of an inquiry into a fire that broke out in a building in Paris in France on Monday night, AFP reported. The toll in the deadly blaze rose to eight on Tuesday, while around 30 people, including firefighters, were injured.

Paris prosecutor Remy Heitz said a woman who lived in the building in Rue Erlanger in 16th arrondissement has been detained. Heitz said police were treating the fire as a possible arson attack.

Emmanuel Grégoire, an official with the city government, said the victims were residents, reported The Guardian. The fire began on the upper floors and then spread to other parts of the building, he said.

“The toll could still increase because the fire is still in progress on the 7th and 8th floors” of the eight-storey block, a fire service spokesperson had earlier told AFP.

Some residents of the building rushed to the rooftop to escape the smoke and flames. “We had to carry out many rescues, including some people who had taken refuge on the roofs,” said fire service spokesperson Clement Cognon.

Fire service personnel also evacuated residents in several surrounding buildings. Around 200 firefighters were still at the scene on Tuesday, battling the blaze.

The 16th arrondissement is an area popular with tourists, with landmarks like the Trocadero overlooking the Eiffel Tower, Paris Saint-Germain’s home stadium Parc des Princes, the Bois de Bologne and upmarket shops and restaurants.
