Chicago, Illinois -- This Amber Alert issued in Dolton, Chicago for the missing teenager Antaneya Smith was canceled around 3:30 am ET after police safely located the girl.

The alert was issued at 11 pm Monday following the kidnapping of the 15-year-old earlier in the day, WTHR reported.

An unknown masked individual abducted the teenager and was last seen driving away in a damaged Ford sedan. The alert was activated at Dolton Police Department's request and issued by the Illinois State Police.

"The Dolton Police have confirmed the kidnapping occurred today, July 11th, at 2:42 pm," the incident's summary read. "Antaneya Smith was kidnapped by an unknown suspect wearing a mask and driving a black 2005 Ford 500 sedan."

Smith is described as a "15-year-old black female, who is 5 feet and 2 inches tall and weighs 140 pounds. She has brown hair and brown eyes." She was sporting "blue jean shorts, white shirt, pink cropped hooded sweater, and white gym shoes."

Smith was taken in a black sedan with Illinois license plate DG20435. Dolton police were trailing the vehicle minutes after the kidnapping. According to the alert, the vehicle was last seen traveling northbound on Interstate 90 and I-94 at 87th Street.

A state police trooper spotted the fleeing vehicle on the inbound Dan Ryan Expressway. The driver managed to escape after sideswiping another car into the side of a state police squad car, reported CBS News.

The injured trooper was taken to a local hospital where he was treated for non-life-threatening injuries.

The delay in issuing the alert raised eyebrows and social media users are blaming authorities for negligence in this case. "This amber alert makes me want police to be prosecuted if they drag their feet on finding children. Her life is at risk, right now this second and they took 9 hours to look for her because they assume Black/brown children run away and will eventually come back. Do your jobs!" read a tweet.

"It took police in Illinois NINE HOURS to issue an Amber Alert for a teen girl who was abducted today. The kidnapper has had ample time to cross state lines with that poor girl! Issue it as soon as it happens. I hope she is found unharmed," read another tweet.

"The child is a Black girl, the least protected in the world. Of course it took 9 hours to issue an Amber alert. What trash," tweeted another. "This poor Baby... I really pray she's safely found. 9 hours is beyond ridiculous to generate an Amber Alert!!" wrote another.
