A partially sighted stroke victim who was shot in the back with a 50,000-volt Taser stun gun in Lancashire by a police officer who mistook his white stick for a samurai sword is launching a bid for compensation.
Colin Farmer, 62, collapsed to the ground in shock and believed he might be dying from another stroke.
The blunder happened after reports were received of a man walking through the town centre of Chorley with a martial arts weapon.
Mr Farmer, who has suffered two strokes and walks at a "snail's pace", was on his way to a pub to meet friends for a drink and did not realise anything was afoot until the officer Tasered him.
On Tuesday his solicitors confirmed Mr Farmer was planning to launch a civil claim against Lancashire police.
In a statement, they said Mr Farmer, from Chorley, had instructed Sophie Khan of McMillan Williams Solicitors to represent him "in his civil claim for compensation against Lancashire Constabulary".
The statement said: "Mr Farmer, who is registered blind/partially sighted and has suffered two strokes in the past, was Tasered by Chorley police officers on Friday October 12 whilst he was out walking in the late afternoon.
"The officers mistook Mr Farmer's white walking stick for a samurai sword and as a result Tasered Mr Farmer in the back.
"The officer involved has yet to be suspended from carrying a Taser despite the fact that the officer involved would need to be investigated for both disciplinary proceedings and criminal assault on Mr Farmer.
"The Independent Police Complaints Commission (IPCC) have indicated that they are conducting an investigation and McMillan Williams will be writing to the IPCC to find out what steps they are taking regarding this serious incident."
