Sabrina Harmes, 32, was last seen in Rishikesh on Wednesday and was in a "confused state of mind", her sister Suzanne Lugano said in a tweet to Swaraj, while seeking her intervention in locating Sabrina.
"We have asked Uttarakhand Government to trace her," Swaraj said in a tweet.
Suzanne, who lives in Nijmegen in The Netherlands, said Sabrina had attended a gathering of a "guru" named Mooji and, when she did not return to the hostel, her roommates contacted the police.
