Just earlier this year, Harigtay was actually mistaken for a New York City Police Department police officer while shooting on location forLaw and Order: Special Victims Unit. While filming the final episodes of the latest season,a witness told Peoplethat Hargitay was approached by a little girl who had gotten separated from her family. The little girl had mistaken Hargitay for a real police officer since she was dressed in character as Captain Olivia Benson.

Hargitay toldPeople back in January, that after playing this character for so long (since the show began in 1999) she’s had “those moments where I’ve sort of slipped into her. If there’s a crisis, I just take over and lead like that. Being strong and fearless." When the little girl approached Hargitay, the actress had apparently paused filming for 20 minutes just to reunite the girl with her family.
