Police in Christchurch are refusing to apologise to a pensioner who was arrested in 2011, despite being told the force used against the man was excessive, unjustified and unreasonable.
John Bennett, 67, was arrested in his underwear in the early hours of 16 December 2011 while carrying an air pistol and tee-ball bat to chase intruders off his Burwood property.
The Independent Police Conduct Authority has upheld a complaint made by Mr Bennett that the arresting officer used excessive force against him by putting a knee and foot on his back to keep him on the ground, which was covered in sewage-infested liquefaction.
District Commander Superintendent Gary Knowles, says he will not apologise to Mr Bennett.
He says he accepts the Authority's findings but feels the internal police investigation was sufficient and the situation does not justify an apology.
Mr Bennett says he has been left humiliated and traumatised by the way he was treated.
