A man died this morning by apparently lighting his bed on fire and suffering burns after smoking while using an oxygen tank, authorities said.



Andrzej Piotrowski, 57, was declared dead a little before 10 a.m. after suffering facial burns at his home in the 3100 block of North Hamlin Avenue, according to the Cook County medical examiner's office.



Piotrowski appeared to have been using an oxygen tank and smoking at the same time, officials said.



Police were conducting a death investigation after the victim's bed caught on fire, apparently killing him, police said.



A Chicago Fire Department ambulance was called to the scene, but Piotrowski already was dead when emergency crews arrived on-scene, said Fire Department spokesman Richard Rosado.
