Ex-RUC officers in policing roles
Over 75% of civilian staff employed by the PSNI on temporary contracts are former RUC officers who retired under the Patten redundancy scheme.
Nearly half of them work in the most sensitive areas of policing, including intelligence, the BBC can reveal.
Sixty-three retired officers have been rehired by the intelligence branch, while 59 are working in the department that investigates all serious crime.
A further 19 are working for specialist operations.
