It’s never too late to do a good deed. A 74-year-old grandfather finally decided to return a pair of handcuffs he stole from an LAPD police officer 60 years ago, with an apology letter and a donation of $100, according to an NBC LA news report.

In the letter, the man recounts being at a Bob’s Big Boy in Van Nuys when he witnessed a scuffle break out between an officer and a “young ruffian.” At some point in the exchange, the officer’s handcuffs came loose and slid across the floor, stopping right at his feet. He scooped them up and has kept them ever since – for six decades.

Flash forward to the present, and the man decided to show the handcuffs to his two grandchildren, who were shocked that he stole them. He attempted to explain himself, saying he regretted it and did the wrong thing, but was still wracked with guilt.

In the letter he said, “They were aghast and asked me why I stole the handcuffs from a policeman. I, of course, had no good explanation and I told them it was the wrong thing to do and I wasn’t proud of it and then I danced around the subject.” He eventually apologized to his daughter and son-in-law, who had a “talk” with the grandkids.

After thinking for a while, he decided to make amends and return the handcuffs with a sincere apology.

The LAPD tweeted a photo of the letter, saying, “this was no ordinary letter. It was a life lesson over 60 years in the making, from a grandfather to his grandkids – that it’s never too late to the do the right thing.”
