"Evangelin - Your country Russia is our time tested friend. My officials in Chennai will provide you all help," Swaraj said on Twitter.
The 24-year-old, who is touring Tamil Nadu, had to resort to seeking alms after he failed to draw money using his bank ATM card as the PIN got locked, the police said.
Evangelin arrived at the Kumarakottam Sri Subramanya Swami temple and sat at the entrance with his backpack and sought alms using his cap.
The police said they gave him some money and advised him to go to Chennai and contact Russian Consulate officials for help.
