Excerpt:
Police are investigating a complaint from a Cardiff mosque which received an uninvited visit from Britain First.
The far-right group posted a video on YouTube showing members in the Al-Manar Islamic Centre in Cathays on 20 August.
The visit followed claims made in national newspapers in July that Shaykh Ali Hammuda, an imam at the mosque, was a "radical" preacher, which he strenuously denied.
Ali Hammuda has been approached by BBC Wales to comment.
