CHICAGO (CBS) — Two people, including a Chicago firefighter, were hurt when a home caught fire near the city’s southern border.

Fire officials said the fire broke out just before 2:30 a.m. at 333 E. 136th St., in a residential neighborhood just south o the Little Calumet River.

The owner of the home, a 37-year-old man, was taken to MetroSouth Medical Center in Blue Island in fair-to-serious condition, officials said. He suffered from smoke inhalation, a Calumet District lieutenant said.

A firefighter was also taken to MetroSouth in fair condition for exhaustion and shortness of breath, Fire Media Affairs Chief Joe Roccasalva said.

Both fire victims were expected to be treated and released, the lieutenant said.

The blaze was extinguished about 3:10 a.m.

The cause of the fire remains under investigation Wednesday morning and the lieutenant said it did not appear suspicious in nature.
