The diplomat, who lost the sight in his left eye after being robbed, has said he will take up his next post as the Governor of Bermuda.
George Fergusson was attacked on Friday evening as he walked in a cemetery in Hammersmith. A 29 year-old man has been arrested on suspicion of robbery and is being held in custody.
Mr Fergusson said he was determined to move to the Caribbean next month to take up the post of Governor despite the attack. "I have been lucky," he told The Daily Telegraph.
"There are still lots of things you can do with one eye - normal day-to-day things.
"It will not stop us going to Bermuda. We are still thoroughly looking forward to it."
He described the attack: "I was running slightly late and I was walking through the park looking at my mobile when a man appeared in front of me demanding my phone," he said.
"He followed up with a punch to the eye and I could feel something pretty bad had happened.
"I fell and he held me down. I was conscious. He punched me a couple of other times as he demanded my wallet, took about £50 and then he left. He did not take my phone."
Mr Fergusson managed to get to Charing Cross Hospital and was later transferred to the Western Eye Hospital. However, doctors were unable to save the sight in his left eye.
