NEW YORK - Katie Couric is losing sleep over some odd 911 calls.
New York City police said Thursday they had been called to Couric's Manhattan home several times recently because of 911 calls traced to a phone listed there.
The 911 operator hears only static, but police are compelled to answer each call.
The calls come on Tuesdays at 2 a.m., as Couric told an audience at her talk show's taping this week, which airs on ABC15.
The New York Daily News reported that the calls are coming from a line under the name of Couric's late husband.
Police say they are investigating whether something's wrong with her phone or if Couric is the victim of a high-tech prankster.
Couric called New York City Police Commissioner Ray Kelly to ask advice on what to do, and is awaiting the results of the investigation.
The calls were first reported in a New York Daily News story headlined "Katie's 911 Hell."
