The father of ex-Sheffield Wednesday striker Dalian Atkinson said he was on 'drink or drugs' when he was Tasered.
Atkinson's 85-year-old dad, Ernest, said the former Owl became agitated and upset in the early hours of this morning.
Dalian, who played for Sheffield Wednesday for a season, scoring 15 goals across all competitions, said his son was 'very agitated' and in a 'real state' when police were called.
Dalian had called at his dad's house in Telford, Shropshire, and was heard banging on the door trying to get inside before police officers arrived and fired a Taser.
"He was in a real state, said Mr Atkinson.
"I don't know if he was drunk or on drugs but he was very agitated and his mind was upset.
"The last thing he said to me was 'don't move' when the police came to the door.
"He was threatening and very upset. I didn't call the police but someone else did.
"He got Tasered in the street outside in the road. I didn't see him but I saw a flash. I haven't had any sleep and cannot take it in.
"The police are dealing with this now."
Dalian Atkinson suffered a cardiac arrest after the Taser was fired and could not be revived.
A neighbour who heard the former football star banging on his father's door and asking to be let in, said the ex-Owl had mentioned being 'homeless'.
A police cordon is in place at the spot where Atkinson was Tasered, with forensic experts examining the scene.
