[1] After his service ended, he joined the Cardiff City Police, later the South Wales Constabulary, in 1947, and it was in this role he was awarded the Albert Medal, which he exchanged in 1972 for the George Cross.
[citation needed] On patrol on 21 June 1948, at around seven o'clock in the evening, he was alerted by a crowd of people that a four-year-old boy had fallen into the Feeder, an aqueduct supplying water to the Cardiff Docks from the River Taff.
Farrow searched the area for fifteen minutes, but thought it was hopeless to venture downstream, and worked his way back to the uncovered section, with the current against him.
He was highly praised for his determination and bravery both by witnesses and the coroner, and was awarded the Albert Medal in October 1948 by King George VI.
He at once ran to the place, divested himself of his police clothing, dived into the Feeder and swam underneath a long concrete covering for a distance of about 180 yards in search of the child.
Although the child's body was not recovered till later, Constable Farrow greatly exhausted himself in the search and in the ordeal of making his way back against the current, with very little facility for obtaining a proper handgrip.
London Gazette, 15 October 1948[3] On retirement from the Police in 1972 as Sergeant, he joined the traffic management section of Glamorgan County Council.
