Amanda disappeared when she was 16, on April 21 2003. She phoned her sister to say she was getting a ride home from her job at a Burger King.
Gina DeJesus went missing at the age of 14, while on her way home from school about a year after Amanda.
Amanda Berry, Gina DeJesus and Michelle Knight had been tied up and held in a home in Cleveland before apparently breaking free yesterday. Police say they appeared to be in good health and had been taken to a hospital to be reunited with relatives and be evaluated. They said a six-year-old was also found in the home.
Michelle Knight, who is now 32, went missing in 2002.
Police said one of the arrested brothers, aged 52, lived at the home. They released no names and gave no details about the others arrested or what charges they might face.
Dozens of police officers and sheriff's deputies are still at the scene awaiting a warrant to search the building where the women and a child were found.
Kayla Rogers, a childhood friend of Gina said: "I've been praying, never forgot about her, ever. This is amazing. This is a celebration. I'm so happy. I just want to see her walk out of those doors so I can hug her."
A neighbor, Charles Ramsey, has been speaking about the release of the women from the house. He said he saw Amanda, whom he didn't recognise, at a door that would open only enough to fit a hand through.
"I heard screaming," he said. "I'm eating my McDonald's. I come outside. I see this girl going nuts trying to get out of a house."
Anna Tejeda, who lives across the road, said Amanda was nervous, crying and appeared dressed in pajamas and old sandals after she kicked through the screen in a door to escape and call police.
Charles Ramsey, the neighbour, said he had cooked barbecue food with the home's owner and never suspected something was amiss. "There was nothing exciting about him - well, until today," he said.
Julio Castro, who runs a grocery store half a block from where the women were found, said the homeowner arrested is his nephew, Ariel Castro. Amanda also named him in her emergency call.
The uncle said Ariel Castro had worked as a school bus driver and he Cleveland school district has confirmed he is a former employee.
Amanda's cousin Tasheena Mitchell said she couldn't wait to have Berry in her arms. "I'm going to hold her, and I'm going to squeeze her and I probably won't let her go," she said.
The press conference in Cleveland is under way and we're hearing from the mayor of the city first.
The mayor, Frank Jackson, says his staff have looked at whether there was any contact with the house or the arrested men before that could have led to the discovery of the women.
He says one of the arrested men reported a fight in the street and police went to the address once but couldn't get in. The mayor says Castro was a school bus driver and left a child on the bus by accident, which is why the police went round.
There are "no indications" that anyone has ever reported suspicious activity at the house, he says.
We're now hearing from police chief Michael McGrath, who says it's "tremendous news" to have found the three women alive and "a boost" for the police department.
He says it is "amazing" that they have found the three alive and well after an emergency call from Amanda.
They have investigated "any and all leads in these cases" over the 10 years the women have been missing. He says Amanda showed extreme bravery in escaping and calling police.
Three men have been arrested: Ariel, Pedro and Onil Castro, the officer says.
An FBI agent is speaking now - he says "prayers have finally been answered" for the women's families.
He says: "Words can't describe the emotions being felt by all. Yes, law enforcement officials do cry."
The case is "horrific", says the FBI agent. He says he will not speculate "as to the how and why" until law enforcement knows the answers.
He is appealing for members of the public who may have information to contact the FBI, saying this is "an ongoing investigation".
The FBI agent says they will focus on the victims and their families, using a special team who are heading to the area.
The media are going to be allowed some questions, but are being warned to be sensitive to the victims and the fact the investigation is ongoing.
The investigation is focused on the local area and doesn't appear to have national implications, police say.
