Griffin probed for tweeting address of gay B&B couple

Police launched an investigation into Nick Griffin last night after the BNP leader published the address of a gay couple on Twitter and urged activists to demonstrate outside their home.

Michael Black, 64, and his partner John Morgan, 59, were yesterday awarded £3,600 after winning a landmark legal battle against the owners of a bed and breakfast who refused to let them share a double room.

But hours later Mr Griffin used Twitter to publish the couple's Cambridgeshire address. "A British Justice team will come up to Huntington & give you a bit of drama by way of reminding you that an English couple's home is their castle. Say No to heterophobia!" Mr Griffin wrote.

The couple were last night in talks with lawyers at the human rights group Liberty, which has backed their campaign, to discuss their next move, but dozens of people are thought to have contacted police on their behalf.

A Cambridgeshire Police spokesman said: "We have received a number of calls in relation to these tweets and are looking into the complaints we have received."

Speaking to i, Mr Griffin denied he was urging his far-right supporters to break the law.

"We are not just against them. We are looking for the judge as well – he's a bloody fool. We are going to wake them up in the morning with loud music and leaflet their neighbours to tell them what a nasty bunch of bigots they are," he said.

Although it is not illegal to post an address online, the threat to picket the private home could fall foul of section 127(1) of the Communications Act 2003, as well as breaching Twitter's terms of service. Users of the social networking site hit back last night by posting the address of the BNP MEP.

Earlier, Reading County Court had heard how owner Susanne Wilkinson declined to let the couple stay in a double room at the Swiss Bed and Breakfast in Cookham, Berkshire, in March 2010 because of her religious views – despite them having made a reservation and paid a deposit.

Speaking before Mr Griffin's comments, Michael Black said: "It feels like a triumph because it has taken two and a half years to get this far so to get the judgment and be vindicated on it is a great feeling."
