15-year-old North Carolina girl found safe following Amber Alert Nevia Nixon was last seen on Sept. 25.

A missing 15-year-old girl in North Carolina has been found after an Amber Alert was issued earlier in the day.

The North Carolina Department of Public Safety sent out an Amber Alert for Nevia Maihyanna Nixon, of Fayetteville, on Thursday morning.

Nixon was last seen on Sept. 25 along the 600 block of Welsh Place, according to police. She was reported as a runaway the next day and Fayetteville police initially issued a "runaway/missing person" notice about her, but the case has since been upgraded to an Amber Alert.

The Fayetteville Police Department tweeted Thursday night that Nixon had been found "safe and unharmed."

Sgt. Ranessa Wallace, spokeswoman for Fayetteville police, told ABC News prior to Nixon being found that the department received "new information that raised concern, as well as she hadn't reached out to family members or friends, so that caused us to raise it to the level of an Amber Alert."

She said it was a possibility that Nixon is in danger.

"We can't rule it out," Wallace said.

Wallace would not say what information police received or where the information came from.

She did note that there had not been a confirmed sighting of Nixon since her disappearance.

Nevia's father, Carton Adams, had pleaded for her return, saying she is a loving girl. Adams said she spends a lot of time on social media, but has not posted anything since Sept. 25.

"I would like to keep positive and believe that my baby is not in any danger, but she loves her family and Nevi would have reached out and came home or said something," he told Durham ABC station WTVD.
