The 17-day hunt for Sarah Payne has sparked a massive nationwide hunt.
Here is a day-by-day account of the operation to date.
DAY 1: Saturday, July 1. At 7pm Sarah goes with her sister and two brothers to play in a wheat field 150 metres from her grandparents' home in West Kingston. Sarah leaves to return alone. Her 13-year-old brother, Lee, follows, but loses sight of her. He sees a white van and a silver Ford Mondeo just after Sarah disappears. She is reported missing at 9.30pm.
DAY 2: July 2. A full-scale search is launched involving 300 people - police with sniffer dogs, divers, soldiers and volunteers - and 150 officers are assigned to Operation Maple. In Cheshire, 250 miles away, a woman helps a "distressed" girl matching Sarah's description and answering to her name in a motorway service station toilet at Knutsford on the M6. In the evening a man in his forties is arrested in Littlehampton and a white van is towed away.
DAY 3: July 3. A man in his thirties from the Crawley area is arrested. Sarah's parents appeal for help finding their "little princess".
DAY 4: July 4. Police continue to question the two men. Sarah's parents make a TV appeal. The Argus offers £5,000 for information leading to her safe return.
