Here is a timeline of key events since five-year-old April Jones went missing.
Monday October 1
7pm - April is playing with friends in the mid-Wales town of Machynlleth when she goes missing. According to witnesses she is taken away in a van or a four-wheel drive vehicle and there are no apparent signs of a struggle.
10.30pm - Dyfed Powys Police issue a statement saying: "We are increasingly concerned for a missing five-year-old, April, who was last seen playing on her bike in Machynlleth at about 7.30pm. April was seen getting into a light-coloured van as it drove off." Hundreds of local volunteers join the search for the little girl, and publicity is raised on Twitter and Facebook.
Tuesday October 2
8.30am - Police reveal more information about the circumstances of April's disappearance. The force said: "Her abduction took place around 7pm in the Bryn-y-Gog estate in Machynlleth. It was witnessed by another young child when April was seen getting into a grey or light-coloured van, or van-sized vehicle.
"At the time of her disappearance, April was wearing a purple knee-length coat with grey fur around the hood, her school white polo top and black trousers."
Local support for the search effort continues, with binmen downing tools to help. A leisure centre is used as a co-ordination point.
12pm - Detective Superintendent Reg Bevan, from Dyfed Powys Police, tells reporters it appears April got into the vehicle willingly. Officers are tackling the "delicate and time-consuming" task of speaking to the children who were with April around the time she was kidnapped, he says.
He also raises the possibility that the vehicle could be left-hand drive, as it appeared that April had got into the driver's side.
Police say they want to make sure that search volunteers are used in a co-ordinated way.
4.30pm - Police announce that a 46-year-old man has been arrested in connection with April's abduction. Mr Bevan says he was detained at about 3.30pm while walking along the side of the road a couple of miles outside Machynlleth. He lives locally and has a vehicle similar to the one described by witnesses who saw April's abduction, Mr Bevan says. He also says the vehicle has been recovered. He says the police's priority is finding April alive.
