Metropolitan Police Commissioner Sir Bernard Hogan-Howe has spoken out after the death of PC Andrew Duncan after a hit-and-run collision.
He said he was "so sad" to hear of the death.
"On behalf of the Metropolitan Police family, I would like to offer my sincere condolences to his wife and children, parents, family and friends.
Andy was a hard working and courageous policeman. He served the community as both a police officer and as a Scouting volunteer.
The night he was injured, he was doing a job that he loved and we all had every right to expect he would return safely to his home and family - tragically that was not the case.
