Two women who went missing as teenagers in the United States 10 years ago have been found alive and well in a house in Ohio.

Amanda Berry went missing in 2003, a day before her 17th birthday. Gina DeJesus, who was 14 at the time, went missing the following year while walking home from school.

Cleveland Police say the girls were located in a house on Seymour Avenue in the city's Second District this morning.

A third missing person, named as Michelle Knight, was also found in the house.

"Gina DeJesus, Amanda Berry & Michelle Knight found alive, talking, appear to be ok," police tweeted.

A 52-year-old man has been arrested.

Local media reports say a neighbour heard the girls screaming and trying to get outside.

When he approached the house Ms Berry told him who she was and asked him to call police.

There was reportedly a child with Ms Berry, and other children in the house.

Cleveland mayor Frank Jackson issued a statement, saying he was thankful the women had been found alive.

"I am thankful that Amanda Berry, Gina DeJesus and Michelle Knight have been found alive," he said.

"We have many unanswered questions regarding this case and the investigation will be ongoing."

More to come.
