The court heard the father-of-one had handed himself in at Wombwell Police Station on 9 August.
During his police interview, he identified himself in some of the footage of the riot shown to him and told officers he had attended the location to “sort out” the occupants of the hotel who would be “better off in their own country”.
Jarvis, of no fixed abode, also said he “got in with the wrong crowd” and did not know “why I did it” before claiming he had been too drunk to remember the incident and that he had been there against his will.
Dale Harris, defending, told the court it was “probably stupidity” that possessed his client to get involved in the riot.
The Recorder of Sheffield, Judge Jeremy Richardson KC, told Jarvis: “Your conduct was shameful, it was disgraceful.
“You exhibited a high level of violence in the context of what was going on.
“You are the father of an eight-month-old infant.
“What a dreadful example you are as a father.”
