Passers-by called emergency services for help, but it was too late: A 23-year-old is said to have killed his 33-year-old roommate in Elsenfeld, Bavaria, and then set the apartment on fire.
The background of the act is still unclear, said the police.
The alleged perpetrator was brought before the investigating judge on Wednesday, who issued an arrest warrant for murder.
The 23-year-old was taken to a prison.
He did not give any information about the motive, it said.
Passers-by saw smoke rising from the apartment on Tuesday and dialed the emergency number.
The fire brigade was able to extinguish the flames quickly.
According to the police, the emergency services found the 33-year-old lifeless in the apartment.
According to the police, the man not only had burns on his legs, but also injuries that were caused by "sharp violent effects of wine".
The 23-year-old roommate was arrested by a patrol in Aschaffenburg on Tuesday evening a few hours after the crime.
