NEWARK, N.J.—The mayor of New Jersey's largest city says he's a neighbor, not a superhero, a day after rescuing a woman from a burning house.

Newark Mayor Cory Booker says he didn't feel brave, but did feel terrified as he dashed through flames with the woman over his shoulder.

Booker returned home Thursday night to find his neighbor's home on fire. He was aided in the rescue by his security detail.

Booker described the rescue as a "come to Jesus moment."

Booker was treated and released from a hospital after suffering from smoke inhalation and second-degree burns on his right hand.

The woman is in stable condition with second-degree burns.

Booker's security detail helped three others escape.

A fire official says the cause of the fire may be cooking-related.

The mayor of New Jersey's largest city said Friday he feared for his life as he helped rescue a neighbor from a fire before firefighters had arrived.

Newark Mayor Cory Booker, speaking on " CBS This Morning," described how he returned home Thursday night and saw his neighbor's home engulfed in flames. A woman was screaming that her daughter was still inside.

The mayor's security detail tried to drag him away, but Booker told them that the woman was going to die, Detective Alex Rodriguez told CBS. "Without thinking twice, he ran into the flames and rescued this young lady," Rodriguez said.

Booker, 42, an up-and-coming Democratic politician who has been mentioned as a possible future candidate for governor, said he feared for his life as the kitchen erupted in the flames and he couldn't find the woman. The woman called out, he said, and Booker grabbed her from a bed and threw her over his shoulder.

"I punched through the kitchen and the flames and that's when I saw Detective Rodriguez. He grabbed her as well and we got her down the stairs and we both just collapsed outside," Booker said.

The mayor described it as a "come to Jesus moment."

Booker said he couldn't breathe after he got outside. He was treated and released from a hospital after suffering from smoke inhalation and second-degree burns.

Booker's thumb and first finger of his right hand were bandaged.

Booker, who is 6-foot-3, was a tight end for the varsity football team at Stanford University, where he got his undergraduate and master's degrees. He got a law degree from Yale University and as a Rhodes scholar also got a degree from Oxford.

The woman Booker helped save is in stable condition with second-degree burns to her back and neck.

"Honestly it was terrifying and to look back and see nothing but flames and to look in front of you and see nothing but blackness," Booker said. The mayor said he now has an even more profound respect for firefighters.

Booker is known for helping constituents, even shoveling snow during a blizzard that snarled his city and the Northeast in 2010.

A prolific social media user, he tweeted late Thursday that he was fine and thanked his followers for their well-wishes.

"Thanks 2 all who are concerned. Just suffering smoke inhalation," Booker tweeted. "We got the woman out of the house. We are both off to hospital. I will b ok."

He then posted a tweet early Friday morning that read: "Thanks everyone, my injuries were relatively minor. Thanks to Det. Alex Rodriguez who helped get all of the people out of the house."

The cause of the fire is not yet known.

Booker has scheduled a 10 a.m. news conference at his home.
