(CNN) -- Three women who went missing in separate cases have been found together by police in Cleveland, Ohio, a producer at TV station WEWS told CNN on Monday night.
One person has been arrested, Jennifer Steer told CNN's Anderson Cooper.
The women and several children were found in a house, Steer said, citing Cleveland police and witnesses.
"I am thankful that Amanda Berry, Gina DeJesus and Michelle Knight have been found alive," Cleveland Mayor Frank Jackson said. "We have many unanswered questions regarding this case and the investigation will be ongoing. Again, I am thankful that these three young ladies are found and alive."
Berry and DeJesus were in their teens when they disappeared in 2003 and 2004, WEWS, a CNN affiliate, reported. It wasn't immediately clear when Knight went missing.
