A handgun was removed from the trunk of missing Florida toddler Caylee Anthony's grandfather's car, MyFOXOrlando.com reported.

Acting on a tip, police took the gun late Friday night from George Anthony's car — parked in his driveway — and brought it to the Orange County Sheriff's Office.

It was not immediately clear what the significance the find will mean — if any — in the missing 3-year-old's case.

The gun could've had Casey Anthony back in jail, MyFOXOrlando.com reported.

Casey Anthony was released Friday just after 10 a.m. EDT after posting $500,000 bond, but a stipulation of her home confinement says, according to MyFOXOrlando: "I will not possess or have in my residence or in my vehicle any deadly weapons. (Examples: firearms, martial arts weapons or explosives.)"

Orange County Corrections contacted the duty judge, Circuit Judge Daniel Dawson. According to Allen Moore, Public Information Officer for the Orange County Corrections Department, Dawson said that he would take no action until he spoke with the judge who issued the bail order. Dawson spoke with Circuit Judge Stan Strickland early Saturday, who said that because there is no indication that Casey knew the gun was in the trunk, the judge did not plan to return Casey to jail, Moore said.

Casey Anthony, 22, of Orlando, is charged with child abuse and making false statements to investigators in Caylee's disappearance, as well as with check fraud in an unrelated investigation.

Caylee, who was 2 when she vanished, was reported missing in mid-July from Orlando. The girl hadn't been seen for a month before Anthony told authorities.

Orange County police have said Anthony's trunk had contained a decomposing body and that it was likely her daughter's. No other charges have been filed against Anthony, however.

Prosecutors asked for a high bond, hoping Anthony wouldn't be able to get out of jail.

Anthony was re-arrested last weekend on check fraud charges, which are unrelated to the investigation into her small daughter's whereabouts and stem from allegations that she used a friend's checks to pay for groceries and other items.

She was scheduled to appear in court Thursday, but the arraignment was canceled, according to Allen Moore, a spokesman with the Orange County Corrections Department. Orange County jail officials later told FOX that Anthony's bond was posted evenly by two central Florida bail bonds agencies.
