Sussex Police described the last seven days as a "sad week", as colleagues, family and friends mourned two "much-loved and respected" officers.
PC Doug Franks, 43, (right in picture) who served as a member of the Bognor Response team, died suddenly at his home in Lee-on-the-Solent on 10 February.
He leaves a son.
Sgt Sean Preston, 50, (left in picture) a custody sergeant in Worthing, died on 12 February.
He had been working from home for several months and was admitted to hospital in January after contracting Covid-19.
He leaves his partner, children and grandchildren.
Chief Constable Jo Shiner said:
“It has been a very sad week for Sussex Police with the untimely passing of two of our police family.
"My thoughts are with Doug and Sean’s families, friends and colleagues.
“Doug was a much-liked and well-respected colleague, who fulfilled his ambition to be a police officer when he joined Sussex Police in July 2019.
"He was proud to achieve independent patrol status a year ago and served to keep people in Sussex safe.
“A popular colleague, he was devoted to his son and his career.
"He joined the force after working as a financial investigator with the South East Regional Organised Crime Unit, where he built strong friendships and was known for his infectious enthusiasm.
"Sean was a highly respected and experienced officer working in a number of roles within the service including Neighbourhood Sergeant at Gatwick Airport and Custody Officer at Worthing and Brighton.
"Sean was a huge character with a great sense of humour he was loved by everyone he worked with and devoted to his family.
“They will both be missed by all who knew them and I am proud that they were able to serve the local community with passion, pride and commitment.”
