A father-of-two who was on course for a £50,000 online betting payout was crushed when his three-year-old son cashed out the money - when he was at just £7.

Unlucky Gary Walter, 24, a Jaguar Land Rover factory worker from Birmingham, used Bet365's mobile app to place a £10 accumulator and soon won his first three games.

But unbeknownst to him his three-year-old son, Archie, picked up his mobile phone and accidentally pressed the cash-out button, which allows customers to close their bet early.

Mr Walter lives with his partner Becky Groves, 25, and their two children Archie and Darcy, aged one.

Ms Groves worked in education before the couple moved up from Swindon to Birmingham.

When each of the 13 bets he had placed all went his way, a horrified Mr Walter ended up losing out on a total of £49,435.34.

The unlucky incident occurred when Mr Walter was strapping little Archie into his car seat and left his phone on the toddler's lap.

Mr Walter said: 'I left him in the back seat next to my phone briefly and when I picked up my phone again and got in the front seat it said I had cashed in on £6.99.

'I was like "what the hell's happened", and then I realised.

'Archie didn't understand he had done anything wrong, he's only three. I didn't say anything until my missus got in the car.

'Archie just loves the yellow button on the app and even since then he has been trying to tap it. He just sees the yellow button and goes for it.

'I watched a couple more of the results come in and at that stage it was already so gutting because it would have been about £500.

'It just got worse and worse as result after result came in.

'I had Arsenal down to win so knowing I didn't have the bet, I was kind of praying for Hull to get a result.

'It was three nil Arsenal at half time so I just turned the TV off. I was too stunned for words.

'After it all happened I said to Archie "you're not going to university", but I was joking obviously.

'There's no point telling him off, he's too young to understand. I've got another accumulator on this weekend so we'll see what happens.

'I won £7,000 on an accumulator once but £50,000 would have been life changing.'

'This would have paid for our wedding and a deposit on a house.'

He added that he cannot wait to tell Archie what he did when he is older.
