Ex-drug addict hands over apology note and $400 in cash to grocery store he robbed at gunpoint 12 years ago

A family who run a grocery store in Nashville were astounded and moved by the actions of a former drug addict and thief who robbed them about 12 years ago.

Somboon Wu, son of store owner Keosavanh Xayarath, explained that an unidentified man came into the InterAsian Market and Deli at the start of September and insisted they take an envelope.

Though they were initially concerned about opening what he handed over, when they did they found a handwritten note of apology, a plea for forgiveness and $400 in cash.

It turned out that the gesture came from the same man who had held up the store at gunpoint and stole $300 over a decade earlier.

The letter read: 'I do not use drugs anymore, and I feel I must make amends to the people I have hurt in the past.'

The man explained what he had done, concluding: 'I hope you will accept this money and find forgiveness. Peace be with you, Anonymous.'

Wu and his father were so moved that they scanned the note and put it on Twitter and Instagram.

Wu explained to WSMV: 'We just want to let him know if he's watching, wherever life takes you, we forgive you for what you did.'
