An anonymous millionaire in Britain is currently putting people to the test by handing out £1000 to those he randomly encounters, The Telegraph reported.

The paper Telegraph spent the day with him whilst he paced the streets of London hunting for 10 lucky recipients.

The reactions were varied, from the stunned to the suspicious to the simply delighted.

He has given away close to £100,000 to people he has met around the world. He hands those that he chooses a sleek card explaining his project and allows them 48 hours to get in touch.

Sometimes he reportedly adds in a treasure hunt for extra entertainment and leaves the invites hidden in bookshops or landmarks and sends clues out from his Twitter account.

Having agreed to maintain his anonymity I met ‘Mr Lucky.’ He is from London, in his late thirties, with dishevelled hair and appeared wearing rolled-up jeans, high-top trainers and with a camera slung around his neck. He earned his fortune working for an insurance company abroad and resigned last year having realised he had more money than he knew what to do with.
