A man has died in a house fire in Brisbane’s southwest.

No one else was in the Middle Park home when the blaze began on Friday night.

“The fire was brought under control by emergency services, and a man was located deceased inside,” police said.

Emergency services were called by a neighbour who saw smoke coming from the house.

“Preliminary info suggests it’s not (suspicious), but the investigation is ongoing so it hasn’t been ruled one way or another yet,” a police spokeswoman said.

No further information was available.
