Prior to his arrest, Del Naja told the Press Association he wanted to attend the protest despite the consequences a potential arrest could have on his music career.
“Being a musician, obviously, there was a lot of trepidation around how we might not be able to travel and get visas,” he said.
“But I thought ‘this is ridiculous’ and then the police making that U-turn to arrest people again, I thought that is even more ridiculous.
“So I’m going to hold a sign today.
“If I get arrested, I feel very confident that if I stand up in court with the right guidance and say ‘this was an unlawful arrest and, therefore, I don’t accept it’.”
