VALLEY STREAM - Fears are mounting over unsolved sex attacks in Valley Stream and Lynbrook.

Authorities say a 60-year-old woman was raped at Valley Stream State Park last Sunday in broad daylight.

Back on Aug. 12, authorities say there were two other attacks during a short period of time. First, police say a man burst into Zsa Laylagian's Lynbrook home and tried to take her pants off and choke her.

Police say the second attack happened 20 minutes later on Mill Road in Valley Stream. A 30-year-old pregnant woman was walking home from the train when she was assaulted. She ran, but the suspect caught up to her, knocked her to the ground and attacked her.

Authorities have put out sketches of the suspect in the Lynbrook assault and in the Valley Stream rape. Police say they're looking into whether the three incidents are connected.

Anyone with information on these crimes is asked to call Nassau Crime Stoppers at 1-800-244-TIPS.
