Detective Constable Henry Kells was shot dead on the morning of the 14th April 1920 in Camden Street, Dublin, shortly after leaving his home. His killer, according to one source, was Paddy Daly, commander of Collins' Squad.
Henry Kells was apparently not a member of 'G' Division but was on plain clothes work investigating burglaries in the city; he had previously been at College St DMP Station (he held collar number 93B), he served throughout in 'B' Division. A Church of Ireland man from Drumlane in Cavan, he was 41 when he was killed. His death brought the number of DMP assassinated on the streets of Dublin to seven in under 12 months; he had principally been on point duties in various city thoroughfares and had been transferred to plain clothes work just a few weeks beforehand.
According to one story he was involved in an identification parade at Mountjoy Gaol in Dublin, investigating the recent murder of Alan Bell, when he was recognised by Peadar Clancy. The next day Kells was shot. His funeral Mass was held at St Kevin's Protestant Church on the South Circular Road, and he was buried in Mount Jerome on the 17 April 1920.
