Police say they have arrested a man suspected of fatally stabbing his AOL chat buddy after she refused to meet him again in person after an initial encounter.

Police say 23-year-old Nimzay Aponte was killed in a Bronx park Tuesday as she sat with a friend. She told police before she died that "Mike" did it, referring to a person she met on AOL's instant messaging service. Police say the two met once and then she rebuffed him but he tracked her down and stabbed her. Her 25-year-old male companion was also stabbed in the arm and was in stable condition.

Police say 35-year-old Dennis Raymond was arrested on charges of second-degree murder and that he was known as "Mike" online. No one answered the phone at the address provided by police.
