ORLANDO, Fla. (AP) – The $500,000 bond posted a week ago for the mother of a missing Florida girl was rescinded after she was taken back to jail on check fraud and theft charges, a bondsman said Saturday.

Orange County Sheriff’s Office investigators took Casey Anthony into custody at her home Friday night, just a week after she was released on bond for charges related to 3-year-old Caylee’s disappearance.

Anthony was being held on $3,000 bond on the new charges of uttering a forged instrument, fraudulent use of personal information and petty theft, Capt. Angelo Nieves said.

According to sheriff’s office reports, Anthony used a friend’s checkbook to buy items at Target and Winn-Dixie, and to write a check for cash in July.

The 22-year-old has already been charged with child neglect, making false statements and obstructing the investigation into her daughter’s disappearance.

“The allegations surfaced during the investigation but we had to do our due diligence,” Nieves said of the new charges.

On Saturday, a bondsman said the $500,000 bond posted for the charges related to Caylee’s disappearance was rescinded in the middle of the night, making it unlikely she will be released again.

California bail bondsman Tony Padilla said the bond was surrendered based on the latest charges, new evidence and “heightened security concerns” that he declined to describe.

Anthony was to appear in court on the new charges Saturday morning, but that hearing was delayed.

Police say Anthony is a person of interest in the disappearance of her daughter, who hasn’t been seen since mid-June. Anthony did not report her daughter missing until July.

At a press conference outside the Anthony family home, Casey Anthony’s attorney called her latest arrest “grandstanding” on the part of law enforcement.

“They are not searching for anyone,” attorney Jose Baez said. “They are disingenuous.”

Several people from a California bail bonds company helped Anthony post bond, saying she might be more likely to talk about her daughter’s disappearance if she were released from jail. But Padilla said Friday he no longer believes the girl is alive.

“Absolutely not,” he said.

“Casey’s attorney, Jose Baez, diligently tried to contact authorities to surrender his client,” said Larry Garrison, Anthony family spokesman. “The arrest and the drama at the Anthony home tonight only added insult upon injury for the family of the kidnapped child.”

The State Attorney’s Office and Anthony’s attorney had discussed granting her limited immunity, according to e-mails from prosecutor Linda Drane Burdick. Under the offer, Anthony would provide statements to investigators, but prosecutors couldn’t use them against her in court. However, they could use any evidence they find as a result.

Burdick said the offer is set to expire Tuesday.
