It was a very kind act, but it is still against the law, police said.
The New York State Police is trying to locate a woman, who gave a police officer $1,000 in cash.
Officer Christopher Maniscalco was responding to a complaint in the town of Guilderland on Sunday, when the mysterious woman approached him.
She asked the officer if he was busy and Maniscalco said he had a moment for her.
The woman said: "Officer. You always are seen around, doing a good job and I wanted to say thank you."
She handed him a card, Maniscalco thanked the woman and went to work. After his shift, Maniscalco took out the letter and opened it.
Inside, was a card and $1,000 cash.
By law, the State Police cannot accept the money and they want she should donate the money to charity.
