A Roman Catholic priest was sprayed with flammable liquid and then set on fire as he said mass at a Lithuanian church, the Herald Sun reports.
Father Remigijus Kuprys, 46, was able to put out the flames with the help of worshippers, but suffered facial burns, according to the paper.
Lithuanian authorities arrested a 42-year-old man for the attack.
''We have reports that he had repeatedly disrupted masses and shouted weird statements. Investigators are deciding on psychiatric tests,'' police officer Mindaugas Juknys told the paper.
The suspect did not resist arrest and could face up to ten years in prison.
No motive was given for the attack.
Kuprys has since been released from the hospital.
