The house was raided after a period of surveillance
A court in Pakistan has ruled that five Americans detained for suspected militant links cannot be deported while judges review their case.
The high court in Lahore said it wanted more information about the case before such an order could be made.
The men were held last week in Punjab province and are wanted in connection with a possible plot in the US.
They have yet to be charged or appear in court and the US is not thought to have yet requested their deportation.
The men were arrested in the town of Sargodha last week.
Police said they had been in direct contact with various militant groups in Pakistan since August and had offered their services for attacks.
FBI officials said they were the same men who disappeared from their homes in the US state of Virginia last month.
Their families reported them missing after finding a farewell video message, showing scenes of war and calling for Muslims to be defended.
