The 34-year-old actor spent some quality time with young girls here and took to Twitter to post a picture as well as the link of the NGO's web address.
"Met some powerful girls today in Delhi at Apne Aap: A grassroots movement to end sex trafficking. Www.Apneaap.Org," Kutcher tweeted.
The 'Two and A Half Men' star is playing the lead in the independent film directed by Joshua Michael Stern, titled 'Jobs'.
The film centers on the titular figure's life from when he was a wayward hippie from Northern California until he became the co-founder of Apple.
The actor has shot scenes in Delhi and Vrindavan as part of the biopic.
Jobs, who died on October 5 last year, came to India 35 years ago on a spiritual quest and spent two-three months here.
