Two serving police constables have died after testing positive for Covid-19, as the Police Federation pleads for officers to be vaccinated. Pc Michael Warren, a 37-year-old father-of-two who joined the Met in 2005, was classed as “vulnerable” and had been shielding at home, working remotely to help his team. He died on Tuesday after a positive Covid-19 test. Police Constable Abbasuddin Ahmed, 40, joined Greater Manchester Police in March 2017 and leaves behind his wife and two young children who are receiving Force support. PC Ahmed, who passed away on Thursday, has been described by his colleagues on the Stretford Response Team as 'the greatest brother in and out of work' and 'such a lovely man who was never seen without a smile on his face.' Officers also paid tribute to Abs' 'pride of being a police officer' adding: "Abs lived up his name meaning 'lion' - brave, loyal, a fighter, protective, and completely fearless. Abs will live in our hearts forever."
