A 17-year-old boy was arrested overnight after stealing a BMW SUV Tuesday in Margate, authorities said on Wednesday.
Alex Exantus, of North Lauderdale, was arrested shortly after midnight on charges of grand theft and burglary of an occupied conveyance.
"It's amazing. (With) all the help and the agencies, and the help with the media and tips that came in, we're able to help resolve this case in a positive manner," Margate Police Sgt. Lorie Eller said.
Police said a 9-month-old baby girl was inside the BMW X1 when it was stolen Tuesday afternoon in the area of Coconut Creek Parkway and Banks Road.
Margate police said a woman had left her car, which had government plates, on outside a post office when the thief got into the driver's seat and drove away.
Alert neighbors in an apartment complex near McNab Road and Florida's Turnpike said they recognized the BMW from live coverage on the news.
One woman, who did not want to be identified, said she saw the car running in the parking lot with the little girl inside.
She recorded the police scene in a video on Facebook.
"My son said, 'That looks like the car that's on TV with the baby in it,'" the woman could be heard saying in the video. "The way the baby was slumped over in the chair, it's like she wasn't alive."
The woman said she called 911 immediately, and the girl appeared to be fine when paramedics arrived.
Police confirmed that the baby was found safe in the vehicle and she was reunited with her parents.
Authorities said Exantus does not live at the apartment complex where the baby was found.
