Police were searching Sunday for three teenagers wanted in connection with a string of robberies near Fort Greene Park in Brooklyn this month.
One attack took place early last Sunday morning and the other two took place late Wednesday afternoon.
In the above surveillance photo, taken on Wednesday, two of the three suspects are clearly visible and the third suspect is running ahead.

The attackers may spend time at the Whitman Houses in Fort Greene.
