It was like being "trapped in a nightmare," says 61-year-old Colin Farmer, a blind stroke victim from Chorley in Lancashire, of his recent run-in with police that ended with him being tased and cuffed for no apparent reason.
After "a number of reports" were received of a man armed with a samurai sword strolling through Chorley, police were dispatched to the scene only to encounter Farmer, who was walking "at a snail's pace" with his white cane.
Giving him no time to explain, officers shot Farmer in the back with a 50,000-volt Taser, sending him crashing to the ground.
"I thought I was going to be attacked by hooligans," Farmer recalled.
Despite his efforts to notify officers of his blindness, Farmer was dragged and cuffed, leaving him bruised both physically and mentally. "[I] was absolutely terrified," he said.
Farmer was taken to hospital by officers who stayed with him throughout his treatment and later drove him to a friend's house.
A full investigation has been launched by the Independent Police Complaints Commission.
