Shark sightings were reported along Rockaway beaches last weekend. Friday the beach was closed in the afternoon near Beach 30 Street when a shark was seen swimming too close for comfort and again on Saturday near Beach 92 Street. The Saturday sighting left people frightened as reports indicate that the shark had a hold of a female surfer’s leg strap before swimming away. The beach was closed for 45 minutes, according to witnesses. Parks officials gave no word about future closings or how they plan to approach possible sightings in the future. Police search the water for sharks on Saturday afternoon.
