A recruitment drive for special constables in the county is under way.
Chief Constable David Crompton and Commissioner Shaun Wright attended a launch event in Doncaster in a bid to find an extra 650 Specials by 2015.
Mr Crompton said: “In South Yorkshire we have the most dedicated and high performing group of specials in the country.
“We use the Special Constabulary for a wider range of duties than almost any other force.”
Commissioner Wright said: “I encourage people from a wide variety of backgrounds to get involved and become special constables, to represent their neighbourhood and help shape the police and community services.”
