Five men arrested following a BBC documentary on the British National Party have been released.
The men, all from West Yorkshire, were bailed pending further inquiries.
One man was questioned about racially aggravated harassment, another was held on suspicion of possessing a firearm, a third with public order offences.
Two men were held on suspicion of conspiracy to commit criminal damage. They will have to report back to West Yorkshire Police at a later date.
The arrests came as 43 MPs, including former cabinet ministers Peter Mandelson and Frank Dobson, backed a motion saying that police must take action against anyone found to have committed a crime in relation to the documentary.
They also called on four BNP members of Bradford Council to resign, arguing that their victories last month were gained "by deception".
The MPs said the BNP members should fight by-elections under what they called "their true colours".
In a separate development, the BNP is considering legal action after its bank accounts were frozen by Barclays.
BNP chairman Nick Griffin says he has received a letter saying that up to 20 accounts will be closed.
A spokeswoman for Barclays was unable to confirm that the accounts had been closed because of client confidentiality.
