The 36-year-old poured petrol over the 38-year-old man in a mosque in the city of Reutlingen, in Baden-Württemberg, before setting him alight. The woman was taken into custody on Sunday, on charges of attempted murder, according to the state prosecutors office and the police.
The victim was admitted into hospital after the attack suffering from severe burns, however his life is not in danger.
According to the police, the victim and the suspect have known each other for some time. The woman claimed she had been sexually abused and molested by the man. He, on the other hand, says that there was a consensual relationship.
On Saturday afternoon, according to the police, the woman's husband and the later victim got into a fight in a room in the mosque. People attending the mosque tried to separate the two men, but were unsuccessful.
The woman then poured petrol from a canister she had brought with her and set him on fire. The man was able to run outside and, with the help of a witness, managed to take off the burning clothes.
The accused and her husband were arrested at the scene. The woman admitted that she had carried out the attack, saying that her motive was the alleged rape. Her husband was subsequently released.
