An innocent blind man was shot in the back with a 50,000-volt Taser by police after they mistook his white stick for a samurai sword.
Colin Farmer, 61, was hit after reports of a man walking through Chorley, Lancashire, early on Friday evening, with a sword. He said he initially thought he was being attacked by hooligans when he was struck by the Taser.
The matter is being investigated by the Independent Police Complaints Commission (IPCC) after Farmer made a complaint to the force.
Farmer, who used to run an architects’ practice, was on his way to meet friends at 5.45pm and was walking in Peter Street near a restaurant. “I was just walking along and I heard some men shouting really angrily and thought I’m going to get mugged. I didn’t know any police were here.
