The Red Devils are taking part a poker rally in the region this weekend and police have been ready and waiting.
A number of police checkpoints have been spotted around the region.
An Nelson Live reader who wishes to remain anonymous says he saw the gang drive past him as he drove to Nelson from Blenheim.
“I nearly got clipped on the way into Nelson.”
He later saw the gang again as he approached Atawhai.
“There were between ten and 12 of them, they got stopped in Atawhai at Clifton Terrace. There was a big cop stop ready for them.”
The Red Devils are a younger chapter and official supporter of the Hells Angels Motorcycle Club.
They pose the possibility of conflict with the long standing motorcycle club, Lost Breed.
If you have any details on the Red Devils presence in Nelson please let us know what you have seen.
