Supporters involved in disorder in Newcastle after last season’s derby against Sunderland have been jailed for more than 45 years.
Of the 76 people so far dealt with by the courts, 45 of the main offenders have been jailed from between four months and 21 months.
Others - including juveniles and first time offenders - have been sentenced to community orders for their role in the disorder, which was broadcast across the country.
All those sentenced by the courts have been given football banning orders of up to six years, ensuring they will not be attending football matches for several seasons.
Police are warning others that getting involved in disorder could see them end up in prison or with a criminal record which could ultimately impact on their future.
Out of the 156 arrested, 57 said they had been to the match and 33 were season ticket holders.
Northumbria Police Assistant Chief Constable Jo Farrell said: “This was very much football-related disorder, the worst in the country last season, and no one wants to see a repeat of those scenes.
“I’d like to reassure people that the disorder which happened after last season’s fixture was unusual, and we took swift and decisive enforcement action to ensure those suspected of being involved were progressed through the courts.
“Public safety is our priority and this enforcement action has resulted in a number of prison sentences and banning orders, ensuring those involved are not at next month’s fixture.
“We know from interviews and court hearings that some of those involved did not set out to cause trouble and many of the younger offenders were first or second time offenders who had not been in trouble with police previously.
“I’d urge people to think about their actions and the impact this could have on their lives, their community and the city in which they live.
“This disorder was in no way reflective of the people who live in the Northumbria Police area or of North-East football supporters, who want nothing more than to support their team in a safe and enjoyable environment.
“We always put safety first, and with this at the forefront of our minds we’re working closely with both football clubs and other partner agencies to prevent a minority from putting the safety of others at risk.”
In total, 93 people were charged with offences following the derby in April, with 17 cases still being progressed through the courts.
