Thousands of cigarettes and a large sum of cash have been found following a search in Gilford.
The PSNI said detectives have recovered a large quantity of cigarettes and cash following the search of a house in Dunbarton Street.
The search was carried out in conjunction with HMRC who seized more than 41,000 cigarettes. Almost £10,000 was seized by police.
Three men, two of them aged 29 years old and one aged 38 years old, were arrested.
The 38-year-old man was arrested for possession of criminal property, facilitating illegal entry into the UK and diverting electricity.
The two 29-year-old men were arrested on suspicion of illegal entry into the UK.
Both are in Home Office detention whilst steps are taken to remove them from the country.
The 38-year-old man was released on bail pending further enquiries.

It is understood those arrested are Chinese nationals.
