Police have identified a number of people as part of an investigation into disorder during the pitch invasion following Saints' play-off semi-final win. 

Earlier this week, police released 16 photos of people they would like to speak to following a number of incidents after Southampton's 3-1 win over the Baggies. 

But now the force has confirmed that four people have been identified so far.

Three of these people identified themselves over the phone and have since been given a date and time for a voluntary interview. 

During the pitch invasion, two police officers were allegedly assaulted with nine separate reports of objects being thrown at supporters. 

The items allegedly thrown include flares and a chair. 

There were also five incidents of affray reported to police.
