Input: PC Andrew Harper, 28, died as he responded to reports of a burglary in Sulhamstead, Berkshire, on 15 August. Lissie Harper led the convoy on the 15-mile route from RAF Benson to Abingdon Airfield in Oxfordshire on Sunday. Writing on Facebook, she said it had been "an honour" to ride with people from across the country in memory of the Thames Valley Police officer. She said: "I wish I could thank you all personally but I hope this will suffice. "I know that it was a long day with lots of waiting in the cold but I can't tell you how proud I was when I saw every biker and pillion lined up waiting to begin. "You have all touched my heart and given me hope again." Mrs Harper thanked the emergency services, the police and the Police Federation for their help on the PC Harper Ride of Respect Facebook page. She also thanked Benson and Abingdon RAF bases and other supporters. PC Harper's funeral was attended by hundreds of people at Christ Church Cathedral in Oxford on 14 October. Mrs Harper said then: "Although Andrew was strong he was also unfailingly kind, a gentle giant with a heart of gold." They had been together for 13 years. At the time of PC Harper's death, they had been married for four weeks. Sunday's ride had initially been organised for a "small group of riders" to celebrate PC Harper's memory. Organiser Sian Sloper said she had been "overwhelmed" by the support.
