He tried talking to the man. "But he was off his face, absolutely on another planet. He must have taken some hallucinogenic drug."
The man, who turned out to be a 28-year-old local, put up a little resistance when Mr Sherie arrested him for reasons of public safety.
However, this was because he had no idea of what was going on, he said.
On arrival at the police station the naked man was given a gown. A doctor was called to check that he was physically ok to be in custody, then he was put in a station cell to detoxify.
Sherie said he discovered that there was also a warrant out for the man's arrest as he had failed to appear in the Westport District Court on June 15.
The man was later taken to Greymouth to appear in court this morning.
Sherie said it was one of the stranger incidents he had attended in Westport.
"It is not often on a cold winter's night that we discover naked individuals walking the streets."
