Crystal Palace have taunted AFTV regular Mr. DT by hanging his 'stolen hat' from the upper tier of the Homlesdale stand ahead of Saturday's 1-1 draw.
Following last year's 2-2 draw between the sides at Emirates Stadium, DT had his hat taken during one of his customary meltdowns to camera alongside host Robbie Lyle outside the ground.
Palace had fought back from 2-0 to rescue a point as scenes turned ugly inside the ground when captain Granit Xhaka turned on his own fans when his substitution was greeted with cheers.
It is unclear if a Palace fan was actually guilty of lifting DT's hat, but clips of the furious YouTuber chasing the culprits later surfaced online.
The headgear was from DT's clothing label 'Behave', and on Saturday Palace fans were happy to accept blame when a similar hat was lowered on a piece of string from the home end as they poked fun at the Arsenal supporter.
It was another disappointing afternoon for the Gunners as they again surrendered a lead against Palace. Pierre-Emerick Aubameyang was on target early on but Palace hit back through Jordan Ayew in the second half before Aubameyang was dismissed.
