The Guyana Police Force has issued a wanted bulletin for 19-year-old Lennox Roberts.
The teenager is wanted for questioning in relation to the murder of Haslington resident David Gentle.
The murder took place back in September.
Gentle, who worked for the Neighbourhood Democratic Council in the area was found lifeless along the roadway with his head almost severed from his body.
