Three further arrests have been made over Thursday’s fatal collision in Gorseinon — bringing the number of men in custody to five.
A 33-year-old man from Gorseinon has been arrested on suspicion of murder, South Wales Police said in an update at 4.28pm on Friday.
A 38-year-old man from Gowerton and a 38-year-old man from Mount Pleasant have both been arrested on suspicion of assisting an offender.
The arrests follow that of an 18-year-old man from Morriston on Thursday, on suspicion of murder and dangerous driving offences, and of an 18-year-old man from Gorseinon on Friday morning, on suspicion of murder and Section 18 grievous bodily harm with intent.
Three of the five men are now held on suspicion of murder.
An 18-year-old man died at the scene following the collision between a car and an off-road bike on Pen Cae Crwn Road at 12.58pm on Thursday. A 19-year-old man was taken to hospital with injuries.
The force said the investigation remains ongoing, and thanked the public for their support during what it described as “a traumatic time for both those involved and the wider community of Gorseinon”.
All roads closed after the incident have reopened, except the lane running alongside Cecil Road, and an increased police presence is expected in the area for some time.
