The Independent Police Complaints Commission has passed a file of evidence to the Crown Prosecution Service after completing its investigation into an incident in Chorley in which a Lancashire Constabulary officer discharged a Taser at a visually impaired man.
The CPS will consider the file to determine whether there is evidence which would warrant any criminal charges.
In October 2012, Colin Farmer, 63, who is visually impaired and uses a white stick, was shot with a Taser by a police officer who was responding to a report of a man seen carrying a samurai sword.
The IPCC independently investigated the incident following a referral by Lancashire Police.
