An anchor for a Mankato television station featured in a slurred-speech newscast that went viral on YouTube and that was featured on David Letterman's show was arrested this week on suspicion of drunken driving, the Nicollet County sheriff confirmed Thursday.

In an e-mail, Sheriff David Lange confirmed a Mankato Free Press report that Annie Stensrud, 28, who works for KEYC, was arrested on suspicion of DWI early Wednesday on Hwy. 14 in Nicollet County. An anonymous tipster had called North Mankato police earlier to report that a possibly intoxicated driver was on the road.

Stensrud was taken to the Nicollet County jail, held for a time and released. Lange told the Star Tribune that she has not been charged, pending the results of toxicology tests.

A video of Stensrud slurring her speech during a Dec. 4 broadcast went viral on YouTube and was featured on Letterman's "Top 10 Signs Your Local News Team Is Drunk." KEYC officials said at the time that she had had a negative reaction to medication.
