Missing five-year-old girl April Jones.

The search for a missing five-year-old girl in a rural area of Wales was stepped up on Thursday, three days after she went missing. Jones was last seen getting into a vehicle on Monday near her home in the rural market town of Machynlleth.

Police have arrested 46-year-old Mark Bridger in connection with her disappearance.

Rescuers appealed for volunteers with "good local knowledge" to search 32 villages around the town as it emerged that the missing girl needs regular medication for cerebral palsy.
