DETROIT -

Detroit police have announced a $17,500 reward to help find a 2-year-old girl whose father reported being carjacked by a thief who drove away with her strapped into a seat.

Detroit Police spokeswoman Eren Stephens said Saturday that one person has donated $15,000 and Crime Stoppers of Michigan is offering $2,500 for information leading to the return of Bianca Jones.

Police have been working with county, state and federal authorities to find Bianca, who was last seen Friday morning in the city's New Center area. Her father reported being carjacked at gunpoint around 9:45 a.m. The vehicle was recovered nearby with the empty child seat still inside.

Police have released a composite sketch of a suspect, described as a light-skinned African-American man who is not clean-shaven.
