At least one person was rushed to the hospital following a harrowing collision on Flatbush Avenue Sunday. Police said that two cars collided right in front of the Marine Park Golf Course early Sunday. Firefighters had to shear off the top of one of the two sedans to free a motorist, who was rushed to an area hospital for treatment. The injuries the two drivers suffered were not considered life-threatening, officials said. It was unclear if any arrests or summonses were filed as a result of this accident as this paper went to press.
