BROOKLYN - Police are now offering a $2,000 reward for information leading to the arrest and conviction of the men who allegedly robbed a 12-year-old boy.

Investigators say three men held up the young boy in front of his mother and 4-year-old sister. It happened on 18th Street in Flatbush on Friday night.

The suspects approached the family and put a gun to the boy's back, according to officials. They then took cash from the child's mother and fled the scene.
