SPECIALIST police officers are searching through bins in the hunt for missing schoolgirl Shannon Matthews.
It is now one week since the nine-year-old schoolgirl went missing from her Dewsbury Moor home.
Up to 50 officers have been brought in to check rubbish on the route Shannon would have taken from home to school.
And police have found no evidence to indicate where Shannon is.
Chief Supt Barry South visited the scene of the extensive searches yesterday.
He said: "Over the next couple of days we’re working closely with colleagues from the local authority refuse department, targeting sites in and around the neighbourhood to make sure we have done everything we can here.
"We’re emptying the bins, checking the refuse to make sure there’s nothing there that could link us to Shannon’s whereabouts.
"Over the past week, we’ve recovered more than 500 items of property. I can say at this moment in time, we believe we’ve not found anything that links directly to Shannon.
"It is about keeping the focus and momentum going in and around the search areas, checking derelict sites and on so.
"I believe somebody out there has a vital piece of information."
Over the weekend police continued to question those closest to Shannon and were also conducting door-to-door enquiries.
Chief Supt South added: "In an inquiry of this nature, we’re going to speak with close family, close friends, anybody that might be connected with Shannon.
"I think the size of the search, the extent of what we’re doing, the resources going in - we’re not going to lose hope.
"My priority has been the same right from the very outset – we are doing our best to locate Shannon safe and well."
The specialist officers are scouring bins between Westmoor Junior School and her home on Moorside Road.
All the bins in the area had been left uncollected so officers could check the contents. It comes after police revealed they have searched more than 200 homes in the area near to where Shannon lives with her mum Karen.
But there has been no trace of Shannon despite family, friends and neighbours joining 250 police officers in the hunt.
The last confirmed sighting of Shannon was as she left Westmoor Junior School at 3.10pm last Tuesday after returning from a swimming lesson.
CCTV footage showed Shannon entering and leaving Dewsbury Sports Centre swimming pool with classmates shortly before her disappearance.
But there have been no confirmed sightings of the nine-year-old since.
Shannon had previously told school friends that she didn’t want to go home.
She had also written on her bedroom wall saying that she wanted to go and live with her father, Leon Rose who lives in Kirkburton.
