Police are searching for a spineless man who they say sexually assaulted a 67-year-old woman after she offered him a glass of water.

According to authorities, the man approached the woman as she was walking into her Queens apartment in the Fresh Meadows section at about 2 p.m. Monday. The woman who wasn't weary of the stranger, invited the man into her home for a glass of water.

When the suspect entered the home, he attacked her at knifepoint and proceeded to sexually assault her, police said.

The man is described as a 45-65-year-old, with a thin build, approximately 5"9' and 160 pounds. At the time of the attack he was wearing black-rimmed glasses, cops said.

Anyone with information about the incident is urged to call Crime Stoppers at 800-577-TIPS. Any calls will remain confidential.
