Firefighters on Friday battled a two-alarm house fire in San Francisco's Castro District while police were in the same area searching for a man with a knife who may have fled the burning home, according to police and fire officials.
The blaze broke out at 112 Eureka St., the fire department said. It has since been contained.
Officers sealed off an area bordered by Eureka, 18th, Market and Douglas streets, trying to locate a man brandishing a knife, officials said. He was later taken into custody. It was not immediately clear if the man came from the burning home.
San Francisco Fire Department Lt. Jonathan Baxter said four adults and two children were displaced by the blaze in the two-story house.
No injuries were immediately reported.
Further information was not immediately available.
