SCOTTISH amateur boxers and former Scottish police cadets, many now holding positions of great responsibility within the nation's police forces, are mourning the recent passing of Sergeant Bob Crozier, BEM, who fully justified the description once given him of being Scottish police boxing's own Jack Solomons in an illustrious career that spanned 45 years.

One of Bob Crozier's former police proteges as a cadet, currently Lothian and Borders Police Superintendent Jim Hay, recalled: ''I knew Bob as a raw recruit and I was at first in awe of his solidly-built, pugnacious-looking character. He looked like a Hollywood movie tough-guy, but I soon learned that behind

his bluff exterior Bob was a fair and kind man whose stern

admonitions about the importance of self-discipline set standards of conduct that many future police officers have carried with them throughout their subsequent careers.''

Meanwhile, current leading Scottish amateur boxing official Donald McNaughton, who was also a police colleague of Bob Crozier, recalled: ''Bob re-established boxing in the Edinburgh police training curriculum after a lapse of many years - he also promoted police cadet boxing championships as part of each young constable's individual character-building programme. Then he went on to promote shows featuring police boxers against top Scottish international fighters at the Fettes Row headquarters gym which Bob himself had set up, and these shows

were sell-outs.

''Bob also promoted shows at the Edinburgh Music Hall and other venues, and by the early 1980s the universally high regard for his ability as an international class referee and ringside judge led to him being elected president of the Scottish Amateur Boxing Association.''

Again, former Scottish welterweight internationalist Malcolm McKenzie, holder of 10 amateur boxing titles won between 1957 and 1966 recalled how Bob Crozier's ability to inspire respect helped the Edinburgh boxer score a famous victory when he was an underdog against an East European opponent.

''On trips abroad we would sometimes try to slip out of camp before a bout for a little socialising, but when Bob was in charge I would never risk his wrath which I reckon was a key factor in my beating that heavily fancied Czech opponent in Czechoslovakia. Bob kept me focused on the bout and nothing else until the final bell.''

Meanwhile, Bob Crozier's British Empire Medal was awarded partly in recognition of the sterling work he did at Edinburgh's Telford College where in the 1960s and 1970s this tough but immensely likeable and charismatic figure was in charge of police cadets who were studying at the North Edinburgh educational establishment.

Working with college staff, Bob and his police colleagues led the cadets on outward bound types of courses to places such as Ben Mhor in Argyllshire.

As part of this on-going process of individual character-building, Bob Crozier organised the Police Cadet Boxing Championships.

Meanwhile, his reputation

as an international referee and boxing judge grew so that he routinely travelled to boxing judging assignments in India

and Japan.

In fact, on one occasion in India, the Crozier skills at

directing traffic learned during his police career in Scotland were employed to good affect in clearing a traffic jam which was in danger of preventing Bob from reaching a boxing tournament on time.

An incident that symbolised completely Bob Crozier's ability to get results by commanding example and willingness to ''get stuck in'' when the occasion demanded it were qualities familiar to all those who worked with Bob Crozier in police training, further education, or amateur boxing.

Bob Crozier leaves a wife and two married daughters.
