Police say there is no evidence to suggest a Manchester man who died after being shot with a Taser was a victim of mistaken identity.
Ice-cream worker Jordan Begley, 23, suffered a "medical episode" after police fired at him with the stun gun when they were called to reports of a disturbance near his home in Gorton.
Officers were dispatched immediately following the call that a man had a knife in Beard Road on the evening of July 10.
After the Taser discharge, Mr Begley was treated by paramedics at the scene before being taken to hospital and he died shortly after.
Greater Manchester Police referred the incident to the Independent Police Complaints Commission (IPCC) and it has been reported that the watchdog is looking at the mistaken identity claim as part of its investigations.
A 25-year-old man of the same name was wanted at the time for recall to prison after he breached the terms of his licence. He had previously been jailed for burglary and for his involvement in a prison riot.
The other Jordan Begley, from Sale, was rearrested by police on July 18 and sent back to jail.
Assistant Chief Constable Dawn Copley said: "We are aware it has been suggested that these events may have involved a case of mistaken identity, but we are not aware of any evidence to support that suggestion at this time.
"We will, of course, continue to work with the IPCC to assist their investigation."
Tests are still being carried out to determine the cause of death of Mr Begley, who had a suspected heart condition.
