Yell County investigators confirm they are following new leads in the disappearance of Brian and Harper Floyd.
In this latest development, deputies arrested the child's mother.
The Yell County Sheriff's Office says Brooke Floyd is charged with endangerment of a minor -- a felony -- and hindering apprehension.
But investigators aren't explaining the circumstances behind the arrest.
It was Friday afternoon when deputies say they found Brooke Floyd, with cuts and scrapes, in an area of the Ouachita Mountains, south of the Blue Mountain Lake, in Yell County.
At one point in the day, she was with her husband Brian Floyd and 10-month-old son Harper.
So far, we don't know how Brooke got separated from the two because detectives won't release that information.
But after deputies found Brooke Friday afternoon, a massive search for her husband and son -- with close to a hundred law enforcement officers -- began.
Sheriff Bill Gilkey says there's reason to believe baby Harper is in danger...that's why so many people are looking for him.
Sheriff Gilkey said, "Well the fact we haven't located the child, there's always the possibility the child is in danger, so we will treat it as necessary. Highly trained members of the FBI and Arkansas State Police are here today working with us. They're very thorough and we gave them an opportunity to do what needed to be done."
Deputies say Brian Floyd is driving a 1998 Chevrolet king cab pickup.
It's dark green in color with Arkansas tags 288TRP.
If you see it, call the Yell County Sheriff's Department.
Brooke Floyd is expected to make her first court appearance sometime this week.
According to deputies, Brian Floyd was also arrested for a crime, just days before his disappearance.
He was arrested for communicating a false alarm, but at this point we do not have details about what happened.
Meanwhile, family members started a Facebook site supporting the search for Brian and Harper.
It's called Team Harper.
