An alert Indian-origin taxi driver in California has saved an elderly woman from being scammed out of $25,000, prompting police to declare that he deserved a “great citizen award”.

Raj Singh, the owner of Roseville Cab, picked up a 92-year-old woman who mentioned that she was headed to a bank to withdraw a large sum of money to settle an Internal Revenue Service debt, CNN reported on Sunday.

Singh, who picked her up two weeks ago, said this sounded very suspicious to him so he suggested to the woman, this may be a scam. She didn’t believe him. He pleaded with the woman to reconsider so they agreed to stop by the Roseville Police Station to ask an officer, they said in a Facebook post.

While the woman waited in the cab, Raj requested the officer to speak with the woman. And when the officer spoke with the woman, she believed that sure, it was a scam, the post said. “I am an honest guy, and these are old people. They need help,” Singh said.
