His family has now issued a statement following the incident. They said: “We are devastated to announce the loss of Dan at the Royal Sussex County Hospital in Brighton following a cycling road accident on January 30 at Hailsham.
“He loved cycling but not as much as he loved his wife Nikki and their two daughters Eloise, aged eight, and Josephine aged six, to whom he was a wonderful husband and father.
“Dan was devoted to them and his family, a much-loved son of Lesley and Roy and brother to Alexis, brother-in-law to Paul, together with his in-laws Derek and Jan.
“He was a proud, loving, supportive and dependable person to his friends and colleagues.
“He was also passionate Blood Donor and supporter of the NHS Organ Transplant Scheme. The family are proud to say that, as per his wishes, this was utilised fully and will have helped numerous people in need.
“We wish to extend their thanks to the emergency services and in particular to the doctors and nurses in the hospital’s intensive care unit.”
Details of Mr Corrick’s funeral will be made available shortly, but in the meantime, the family have asked that their privacy is respected during this difficult time.
