Mayor Cory A. Booker of Newark carried a woman out of a burning house and was treated for smoke inhalation on Thursday night.

Mr. Booker arrived to his home in the Upper Clinton Hill neighborhood to find a neighbor’s house on fire, said Anne Torres, a spokeswoman. The Fire Department had not yet arrived, she said, and Mr. Booker went inside with two members of his security detail and rescued one woman. The mayor was treated at a hospital and released at 11:30 p.m. “Everyone is O.K.,” Ms. Torres wrote in an e-mail.

Mr. Booker, in fact, was well enough to post a Twitter message. “Thanks 2 all who are concerned,” he wrote after 10 p.m. “Just suffering smoke inhalation. We got the woman out of the house. We are both off to hospital. I will b ok.”
