Police searching for five-year-old April Jones have said their priority remains finding her alive after they tracked down and arrested a 46-year-old man.
Detective Superintendent Reg Bevan, from Dyfed Powys Police, said the man was detained while walking along the side of the road a couple of miles outside the mid Wales town of Machynlleth.
He lives locally and has a vehicle similar to the one described by witnesses who saw April's abduction, Mr Bevan said, and this has now been recovered.
Mr Bevan said: "We were pursuing a number of inquiries, some of those were searching addresses. We were looking for this individual, so we knew who we were looking for and as a result we have had a number of patrols in the area and we have come across this individual."
April was last seen by another child getting into the driver's side of a grey van in Machynlleth at about 7pm on Monday night.
Police said it appeared that she had got into the van willingly, but they did not know if she was led to the vehicle or went there herself.
Asked whether the man arrested has any links with April's family, Mr Bevan said: "It's very early stages. He is clearly a local man, it's a small community, I wouldn't like to speculate further, but I may have some more information later on."
The force's priority remains finding the little girl alive.
"We are still pursuing all lines of inquiry with a view that April is still alive and we will continue to do so until we find her," Mr Bevan said.
He went on: "We will not focus all of our efforts just on this individual. He is significant clearly, that's why we've arrested him, but we will still be pursuing all other lines of inquiry."
