Police are investigating comments made on Twitter by BNP leader Nick Griffin about a gay couple at the centre of a landmark legal ruling.
The MEP published the address of Michael Black and John Morgan on the social networking site and called for a demonstration to be held outside their home.
Cambridgeshire Police were watching the house this morning and confirmed that they were working with Dyfed-Powys Police to investigate the incident.
In a series of new tweets this morning, Mr Griffin appeared to make light of the matter, implying that the police were only investigating his comments because gay rights campaigner Peter Tatchell "can claim" to be offended by them.
His Twitter account seemed to be working normally after is apparent suspension last night.
Mr Griffin confirmed to ITV News that he did send the messages, but said he has "no idea" if his account had been suspended, admitting he was "too much of a technophobe to find out."
Speaking on BBC Breakfast, Michael Black hit out at Mr Griffin for his comments:
Mr Griffin's tweets followed Mr Black, 64, and his 59-year-old partner Mr Morgan's legal victory against the owner of B&B accommodation who refused to let them stay in a double room.
The couple, from Brampton in Cambridgeshire, sought damages from Susanne Wilkinson after she would not let them have the room at the Swiss Bed and Breakfast in Cookham, Berkshire, in March 2010 despite them having made a reservation and paid a deposit.
A court found Mr Black and Mr Morgan, a computer consultant, were discriminated against and awarded them each £1,800 which the men said would be donated to charity.
After the couple won their court ruling, Mr Griffin tweeted:
His comments prompted a furious response online, including from the gay rights charity Stonewall:
Cambridgeshire Police said they were looking into complaints about comments.
However, Mr Griffin told ITV News he was not concerned that police are looking into the matter.
