Daniel has been missing for five days

The grandfather of missing seven-year-old Daniel Entwistle has made a fresh plea for help in finding his grandson.

Keith Button, the father of Daniel's mother Paula, urged visitors to the boy's home town of Great Yarmouth to check photographs and video pictures they may have taken since last Saturday.

Daniel disappeared at about 1700 BST on Saturday.

His bicycle was later found by a river in the town.

Mr Dutton told a news conference on Thursday: "Although I'm Daniel's granddad, I am also Paula's dad.

"And basically I am seeing her go through hell."

He's our little boy and we just want him back David Entwistle, father

He asked people to double check pictures they had taken in Great Yarmouth, in the hope they may have caught an image of Daniel.

"If you have been taking photos, could you please look through them and compare them with photos of Daniel?

"If you think there is the leanest, slightest chance that you might have caught an image of Daniel, please contact the police.

"You are not wasting their time."

Daniel's father David, 41, told the news conference: "He's our little boy and we just want him back.

"I have just got to be strong for Paula because she's not well at the moment and she's going through hell."

'Send him back'

He said the possibility that their "special little boy" was still out there and alive that was keeping them going.

"If somebody is actually holding Daniel just send him back.

"If you want to take him to a local police station in the country please by any means do that, just take him there and leave him there."

He praised the help from his local community and the support from the public.

Mr Entwistle said Daniel was not the type to run away. He said his son suffered from Attention Deficit Hyperactivity Disorder but he would not voluntarily have gone off with a stranger.

Police divers have used sonar equipment to search the River Yare, but Mr Entwhistle said that Daniel did not like water.

"If he had gone into water it's a complete tragedy; he could not swim at all."

Detective Superintendent Julian Gregory, who is leading the hunt, said on Thursday: "We certainly have no plans to scale down our resources.

"We will start to think about that when we have exhausted everything we can do."

He added: "The longer he is away the more we are worried. But there is still hope."
