Seven arrests were made at today’s East Anglian derby against Norwich City, Suffolk Constabulary has announced, including two relating to the flares which were lit during the first half of the game, which ended 1-1.
A 34-year-old man from Ipswich was arrested for discharging a flare in the stands, while a 45-year-old man from Norwich was arrested for possession of a lit flare.
Police say several people required treatment by medics for the effects of the flares, but all are understood to be OK.
A Town spokesman said in a statement: "We obviously condemn the idiotic behaviour of those who set off flares inside the stadium and are working closely with the police to identify the culprits.
"We understand two arrests have already been made over the matter."
Meanwhile, a man from Norwich, 23, was arrested on suspicion of possession of class A drugs, while a 23-year-old man from Colchester and a 57-year-old man from Witham were arrested for breaching a section 35 dispersal notice to leave a designated area following anti-social behaviour.
A 29-year-old man from Felixstowe was arrested on suspicion of affray and a 23-year-old man from Norwich on suspicion of assault. All those arrested were taken into custody at Martlesham Police Investigation Centre.
Chief Superintendent Louisa Pepper said: "A very small minority appeared to be set on causing trouble and officers made several arrests during the course of the policing operation today.
"We said before the game that we would not tolerate anti-social behaviour, violence, racial chanting, mindless vandalism or any alcohol-fuelled disorder and the vast majority of the 25,000 who attended were responsible and respectful.”
