Large police presence as Southampton FC play Millwall

The St Mary's match got underway at 3pm.

See our gallery above of the police presence today.

Police on the ground have been authorised to use dispersal powers.

This would give officers the power to order someone who is likely to cause harassment, alarm or be involved in crime and disorder to leave the area and not to return within a specified time period.

These are given under Section 34 of the Anti-social Behaviour, Crime and Policing Act, and would apply between 9am and 11pm on Saturday.

Those who refuse to comply with the orders would be committing a criminal offence and would be liable for arrest.

Police will also have powers to order those causing disruption to reveal their identity should they be wearing anything which wouldn’t identify them, like balaclavas.

This would help to tackle those police believe are out to commit anti-social behaviour or crime.

These are powers under Section 60AA of the Criminal Justice and Public Order Act 1994, which according to the police, are not commonly used in the county.

The powers apply to a specific area which covers the city centre, St Mary's and the Polygon.

Superintendent Mark Lewis, Match Commander, said: “This is an exciting event for football fans, particularly those who will be attending St Mary’s Stadium to watch the game.

“We are grateful to the majority of spectators who wish to enjoy the game, behave responsibly and are respectful to one another. Regrettably, we do know that a small minority of fans do choose to behave in a way that falls far below the standards we expect.

“We have robust plans in place in partnership with the football club to make this a safe event for all, and to disrupt any individuals involved in poor behaviour that risks the safety of themselves and others.

“You will likely see our officers out and about as they engage with fans and, where necessary and proportionate, use the powers authorised to deal with any ASB or criminality."
