Two Afghan nationals employed to act as Taliban fighters on a British military base have been arrested after claims they are illegal immigrants.
Officers from the Ministry of Defence Police and the UK Border Agency made the arrests at Rollestone Camp on Salisbury Plain, Wiltshire.
An MoD Police spokesman said: "On Tuesday 26 MoD Police in conjunction with the UK Border Agency carried out an intelligence-led operation on Salisbury Plain.
"MoD Police officers arrested two people on suspicion of immigration offences.
"Both suspects were taken to a police station and handed over to the UK Border Agency."
The Afghans were employed by an outside contractor and were on short-term contracts, the MoD Police spokesman said.
It is understood their wages would be paid by the MoD through the contractor.
They had been hired to act as enemy fighters during training exercises for troops preparing to be deployed to Afghanistan.
During the exercises they were given prop weapons as they launched mock attacks on the troops.
