After a fire in an apartment building in Berlin-Neukölln with several injuries, the State Criminal Police Office is investigating on suspicion of arson.
The fire broke out on Friday evening in the stairwell of the residential building, as the fire department announced on Saturday.
According to this, an electric wheelchair on the ground floor of the building on Karl-Marx-Strasse is said to have caught fire.
Fires also broke out in two other nearby houses shortly before and shortly after, but no one was injured there.
According to the fire brigade, a person jumped from the first or second floor of the largest fire and was critically injured.
The police initially had no information about this in the afternoon.
According to a spokesman, eight people suffered from smoke inhalation, four of whom needed hospital treatment.
According to police, a 38-year-old man noticed the fire as he drove by in his van and parked the car in front of the building so people on the first floor could climb over the roof to safety.
Emergency services had to break into apartments to get residents out of the house, it said.
During the operation, there was a fire in another hallway of a nearby apartment building, the police said.
Local residents are said to have extinguished burning prams there before the fire brigade arrived.
Nobody got hurt.
About an hour before these two operations, firefighters also extinguished a burning garbage can in the courtyard of a house.
In all three cases, the fire department is now investigating at the State Criminal Police Office.
