Arnold passed away aged 91 years-old. He is believed to have been one of the club's longest-serving fans having begun supporting the Bantams aged only 12.
The loyal City follower was a season ticket holder at the Coral Windows Stadium for 79 years and still attended games as recently as last (2013/2014) season.
His funeral is scheduled for 11:00am on Tuesday 3 June at Rawdon Crematorium.
The thoughts of all of the club staff, players and directors at Bradford City Football Club are with Arnold's family and friends during this testing time.
