A man has been charged with robbing a friend of Prince Harry as he chatted to him on the phone in the street.
The Prince drove to help Thomas van Straubenzee after the incident in Battersea, south west London, in November.
When he could not find him, he searched for his friend until he found him in a local police station, reporting the crime. Harry, 27, then gave a statement to detectives.
A Metropolitan Police spokesman said: "Winful Taylor, 27, of Streatham, was today charged with robbery on November 30 2011 in Albert Bridge Road.
"He will appear at South Western Magistrates' Court tomorrow."
At the time, a Clarence House spokesman said: "Prince Harry joined a friend at a police station in south London after his friend had reported a robbery.
"By the time Prince Harry arrived to be with his friend, the police investigation into the incident had already begun."
Mr van Straubenzee, who is also close friends with Prince William, first met Harry at Ludgrove Prep School.
Mr van Straubenzee, also known as "Van", accompanied the Prince on his first official tour to New Zealand.
The royal brothers are patrons of a memorial fund dedicated to Mr van Straubenzee's brother, Henry, who was killed in a car crash in 2002.
