Up to 40 of Ben's family and friends have been helping with the police
search from 10am to 8pm every day.
Lee, who is managing the 'Find Ben Manning' Facebook site, said: "They are coming home after the search and they were exhausted, but they physically can't sleep through worry. My mum will not stop until Ben is found. She will go out searching every single day."
He added: "Mum is keeping herself together really well, she is a very strong woman."
Lee said police and helpers yesterday searched Thornes Park for a second time and have covered the entire Eastmoor area and Pinderfields Hospital grounds.
He added: "The police are calling it a spiral search, out from where Ben was last seen near JCT 600 garage on Denbay Dale Road. They have concentrated on the CCTV footage and have worked on covering the rivers and open spaces, going round in a circle from where Ben has been seen."
