Cory Booker, the mayor of Newark, N.J., who's become an Internet legend for his Twitter antics and real-world heroics, added another act of valor to his resume Thursday: He saved a freezing dog left in the cold during a below-zero night.

The dog was brought to Booker's attention by local WABC reporter Toni Yates, who tweeted a plea for help to the mayor. Yates was using Twitter to help residents without heat, while Booker had been tweeting to advise people about staying warm.

#pets cold Yay! Newark for its heat help. Make pet owners get their dogs out of the cold. Saw 2 dogs freezing @eyewitnessabc7 @corybooker — Toni Yates (@ToniYates7) January 24, 2013

@delia716 @corybooker @darlamiles7 I asked the block captain to do something, call someone. Doubt he will. Sad. — Toni Yates (@ToniYates7) January 24, 2013

Booker saw the message and decided to help in person:

I'll head up myself & investigate RT @toniyates7 Madison Ave bet S 11 & 12 and 856 S 12 - 2 dogs left outside, freezing. No answer shelter — Cory Booker (@CoryBooker) January 24, 2013

Before long, Booker was on the scene, ready to rescue the endangered pet:

Mayor Booker saves the day and the dog.. from the cold. The owners speak at 11:00 @corybooker @darlamiles7 twitter.com/ToniYates7/sta… — Toni Yates (@ToniYates7) January 25, 2013

"This is brutal weather," Booker told WABC. "This dog is shaking really bad and you just can't leave your dogs out here on a day like this and go away and expect them to be OK. Hypothermia on any animal including a human animal will set in pretty quickly. So this is very sad. You can just feel the dog shaking pretty badly."

Booker put the dog in a heated police car, called its owners and scolded them for leaving the dog outside. The owners said they were away from home and didn't know how the dog, named Cha Cha, got out of the house. They apologized to Booker.

Because of you that dog was rescued. Thank you for reaching out. Thank u for your kindness RT @toniyates7: 2 dogs left outside, freezing. — Cory Booker (@CoryBooker) January 24, 2013

Here's more from WABC:

Booker's list of previous thrilling heroics include saving a woman from a burning building and shoveling snow for Newark residents.
