The family of a policeman killed in a hit and run in Sutton have paid tribute to a "fantastic husband, father, son and brother."

PC Andrew Duncan, known as Andy, died in hospital on Sunday, two days after he struck by a speeding car he attempted to stop in Reigate Avenue, close to Rosehill, in Sutton.

The 47-year-old who was married with two children, joined the Metropolitan Police force in March 1990 and was originally posted to Battersea.

Six years later he transferred to the South-West Territorial Support Group where he served for almost seven years before moving to Hammersmith and Fulham Borough.

In May 2004, he joined the South-West Traffic Unit.

His wife Claire said in a statement: "We would like to thank all the medical staff at St George's Hospital, Tooting, for their enormous efforts in attempting to save Andrew's life.

"We have had, and still are having tremendous support from all Andrew's colleagues, family and friends. Our children, Adam, Emma, and myself are truly grateful.

"Andrew was a fantastic husband, father, son and brother. This is supported by the many tributes which we are still receiving from his family and friends.

"We are left with a huge void in our lives, but we have some fantastic memories that we will always treasure."
