An elderly Taiwanese man has rigged up 11 smartphones on his bicycle to catch hundreds of digital monsters a day playing Pokemon Go.

Chen San-yuan can play up to 20 hours in a row before his phones and nine power banks carried in his bike's basket run dry.

The 70-year-old trundles along the streets of Taiwan, sometimes until 4am, throwing the digital pokeballs at his quarry with a flick of his finger.

The Feng Shui master said he spends about £1,165 a month on his many Pokemon Go app purchases and the equipment needed to power his gear.

His favourite spot is a park he visits five or six times a week and shot to fame online when a local posted a snap of him to Reddit.

Chen earned the nickname 'Uncle Pokemon' but was unaware of his cult following when Taiwanese TV station EXP.GG caught up with him.

He said playing the game helped him stave off Alzheimer's disease and connect with other players in his old age.

Chen became hooked on Pokemon Go in 2016 when his grandson taught him how to play the game.

He now plays it so much he only puts accounts above level 30 on his bike, hoping to mount 15 phones on it before long.
