Video: Players in brawl with their own fans as violence breaks out in English Rugby League clash
Any "thugs" found to have been involved in trouble at the end of Salford's win at Huddersfield will be dealt with, according to club owner Marwan Koukash.
Shortly after the Red Devils had beaten the Giants 26-24, photographs emerged on social media of some of Salford's players becoming embroiled in ugly scenes with some of their own supporters in the away end of the ground.
Pictures on Twitter showed winger Justin Carney and centre Junior S'au involved in heated exchanges, with one particular photo showing New Zealander S'au appearing to restrain a fan on the ground.
Press Association Sport understands the two players in particular were concerned for the welfare of their families who were sitting close to where an alleged incident of crowd trouble had taken place, and as such went into the stands to check on them, leading to further scenes of confrontation.
Salford reacted swiftly to the incident and owner Koukash has pledged to get to the bottom of what went on.
He said in a statement: "I want to apologise to the Huddersfield Giants and to all the decent fans at the game today.
"We will work closely with the Giants and the RFL in our investigation and this minority of thugs responsible will be identified and dealt with by the club in the coming days. There is no place in Rugby League for them."
The Rugby Football League is also to start its own investigation.
Commenting on Monday night, RFL chief executive Nigel Wood said: "We will conduct a full investigation into the events that took place in the away section of the crowd at the game between Huddersfield and Salford.
"We do not condone violence of any kind and will ensure that anyone found to have acted improperly is dealt with accordingly."
Press Association Sport contacted West Yorkshire Police without comment.
