He was attacked near his £180,000 Bentley Continental after arriving in the park to look for his elderly brother. His brother Thomas, known to his family as Noel, suffers from dementia and had left his nearby house. After Noel had been located safely, members of the family then went looking for Mr Power, who had not returned.

His head was covered in blood and his face was already beginning to swell up. He was conscious but could not speak or communicate in any way.
