Burrows modernised and diversified the force, introducing a police dog section in July 1959 and asking for his foot patrol officers to be equipped with portable police radio. New motorcycles were introduced, including a 1957 single-cylinder Royal Enfield, two 1958 or 1959 Triumph twins and a 1959 or 1960 Triumph twin. New cars included a Morris Isis, a 1959 Wolseley 15/60 saloon and 1962 Morris 1100. Burrows introduced the city's first portable speed radar in 1961. With it his officers caught 508 offenders in the second half of that year. In 1964 Traffic Wardens were introduced, and a telex machine was installed in St Aldate's police station. The dog section used German Shepherds. Initially it had only two handlers and two dogs, "Kim" and "Danko". In 1961 "Kim" contracted an incurable eye infection, was put down and replaced with a new dog, "Kim II". In 1962 the section was doubled with two additional handlers and their dogs "Micky" and "Rex". "Danko" was the force's longest-serving dog. In his career he made 30 arrests. But in 1965 he suffered a leg injury and had to be put down. In 1966 "Micky" retired from the force with his handler. They were succeeded by a new handler with the Oxford force's final dog, "Kelly". In his Annual Report for 1957 Burrows had said he wanted beat officers to have portable radios "within five years". In fact they were not introduced until November 1965. Until then the force had a network of Police telephone pillars. These were soon removed except for one at Carfax, which survived until at least 1979. The force was growing and was restructured into three divisions. "A" Division was administrative, "B" Division policed central Oxford and "C" Division policed Cowley. The original Cowley police station was replaced by a new one in Oxford Road that was opened on 14 September 1966. Drug abuse was an increasing problem, notably among some of Oxford's students. In 1967 the Oxford force formed the country's first drug squad. Since the 1930s most of the Oxford force's police cars had been built by the Nuffield Organization: Morris, MG, Riley and Wolseley. In its final year the force changed its practice by acquiring from Hartwell, a local dealer, four of Ford's newly-introduced Escort Mk I saloons. From the late 19th century to the mid 20th century many incorporated boroughs in Great Britain had their own police forces.
