"Intelligence was gathered that a targeted and organised large-scale fight took place over two months ago in Lower Broughton in Salford before heading towards the city centre," a statement from GMP read. "With the Manchester derby only days away, this is another strong reminder that violence of any sort, whether it’s linked to football or not, will not be tolerated."
Chief Superintendent Colette Rose added: "With another big fixture coming this weekend, we want to send a strong message and reassurance that our specialised officers will be deployed to ensure you remain safe and peace is maintained, so you can enjoy the game. On occasions when enforcement is needed, those who are intent on causing harm will have to answer for their actions."
