Federal and Detroit officials continued to search Sunday for two-year-old Bianca Jones, who was allegedly kidnapped during a carjacking, the Detroit Free Press reported.

The toddler's father, 32-year-old Deandre Lane, told police a man with a gun seized his silver Mercury Grand Marquis Friday morning and drove off with the child buckled into her car seat.

The car was recovered just ten minutes later, less than a mile from the site of the alleged carjacking, but the little girl was gone.

According to a statement released by Police Chief Ralph Godbee, Lane's story remains in question.

"The Detroit Police Department will not comment on the quantity nor the quality of any evidence or information we have gathered to date," Godbee said, according to the Free Press.

"However, in the interest of allaying some of the fears of the public regarding the apparent randomness of Bianca's disappearance, the authenticity and credibility of the original version of events is under intense scrutiny by our investigative team."

A reward for information that leads to the child's return was increased to $17,500 after an anonymous donor contributed $15,000, myFOXdetroit.com reported.

Godbee also said the search remains "priority one," the Free Press said.

The newspaper said Detroit police, along with the FBI, Michigan State Police, Wayne County Sheriff's Office and several community groups are scouring the city for the little girl.
