Arial Castro was "interviewed extensively" over the boy he left on his bus during a lunch break, police say. There was no criminal intent found, they say.
"The real hero here is Amanda... she is the one that got this rolling," he says.
There are "other properties that we're interested in", he says. Mr Tomba says he hasn't been in the house as it's a crime scene.
The child found with the women is Amanda's child, Tomba says.
Tomba says the women will have to tell them what went on in the house. He says police have spoken to all the family members of the three, but he will not reveal details.
He says "obviously the door was secured" at the house but can't say exactly how. He says Amanda broke out of the bottom of it.
The women were in need of a good meal, Tomba says, but there were no other obvious signs of maltreatment.
The police must make a charge within 36 hours of an arrest after an agreement with a prosecutor, police say. Tomba says he expects a grand jury to be involved.
The three arrested men have not been interviewed yet, he adds.
One of the arrested men had the house where the women were found as his driving licence address, the other two had different addresses, police say.
Police chief Mike McGrath is speaking again. He says the victims and sensitivity to them and their "emotional wellbeing" is paramount.
We're being told that some of the homes around the house where the women were are abandoned and police will likely be searching them. There was some disturbed earth behind it as well, reports suggest.
Juan Perez lives near the house where the women were found. He told NBC: "I thought the home was vacant. I thought he probably had another property and he would just come and check and see if everything is OK. I didn't even know anybody lived there."
Authorities declined to say whether the women were restrained or if any of them had been sexually assaulted.
Amanda's mother, Louwana Miller, died in March 2006 having spent the previous three years looking for her. Councillor Dona Brady said she had spent many hours with Miller, who never gave up hope. "She literally died of a broken heart," she said.
That image of two of the women who have apparently spent about a decade in captivity is where we're ending our live coverage for today. Thanks for following.
