Oxford started a crack-down on street robbery at the end of June in conjunction with Operation Brush against anti-social behaviour in the city’s parks.
Operation Buzzard is now in its third year and Thames Valley Police say that last year there was a 32 per cent decrease in crime as a result.
The police work with community and city associations to patrol crucial areas in the city with specialist units.
Oxford attracts a large number of tourists and overseas students learning English during the summer. Police have reminded visitors that at night they should avoid walking home alone, and be careful if they are using mobile phones or headphones.
Operation Brush in the parks also tackles problems of litter and under-age use of alcohol.
