Police were called to a smoking toilet block at the Dunedin bus hub early on Thursday morning.
Senior Sergeant Anthony Bond, of Dunedin, said police were called to the cubicle by a street cleaner about 4am.
When officers opened the cubicle to extinguish the fire, they found a 31-year-old man lying on the ground with a small pile of items burning next to him, Snr Sgt Bond said.
‘‘Police extinguished the fire and arrested the male.’’
A formal warning was issued and the man was referred to probation for breach of his release conditions, he said.
