Morgan was also knocked to the floor while Roach was punched in the face and suffered a nasty cut below the eye which required stitches.
He was seen sporting a bandage to protect the wound as the World Cup action continued following the unsavoury incident on Sunday. Langkilde was suspended by Samoa for the World Cup's final day on Sunday, but was then later arrested at his team's hotel at 1.15pm on the same afternoon. It is understood Wales' players are determined to pursue the matter.
"The boys want to take this all the way," a Wales source said. "There was nothing in the game which suggested this sort of thing might happen so it came out of nowhere."
San Francisco Police's investigation remains ongoing and it remains unclear what punishment awaits Langkilde both from a criminal and rugby perspective. Asked to provide an update, World Rugby stayed tight-lipped and refused to add their original statement which was issued soon after the incident took place.
The statement read: "We can confirm a Samoa player has been provisionally suspended from Rugby World Cup Sevens 2018 following an initial investigation into an alleged incident in the tunnel area after a match between Samoa and Wales at AT&T Park on Saturday.
"The alleged behaviour is not aligned with the sport's values and the excellent spirit in which this competition has been played by the 40 participating teams. "World Rugby has instigated an investigation and the Samoa player will remain provisionally suspended until the final conclusion of that process."
