Brisbane protester fined after super glue stunt

He's the protester who really likes to stick around.

Eric Serge Herbert, 19, caused traffic delays for three hours in Brisbane on Tuesday when he and a woman superglued themselves to a zebra crossing in the CBD.

Then he would not leave the watch-house after his arrest, refusing to sign his bail undertaking when police tried to release him.

So he fronted Brisbane Magistrates Court on Wednesday after spending the night in the watch-house.

"He was offered bail but like a true armchair revolutionary he wasn't going to sign it," magistrates Suzette Coates said.

Herbert pleaded guilty to public nuisance and contravening a direction.

He was fined $550 with no conviction recorded.

Ms Coates asked if the woman he'd glued himself to the road crossing with was his girlfriend.

He replied "maybe in the future".

"She's obviously someone who you, shall we say, feel some magnetism towards," Ms Coates said.

Herbert, an unemployed former university student who is supported by his parents, told the court he was protesting the "genocide of life on earth".

"I don't care what punishment I get. Nothing's going to stop me from doing this again," he said.

During the protest on Tuesday, he told AAP they were protesting against "an extinction".

"I can't live with myself knowing that's happening and not doing anything about it," Herbert said.

Police and paramedics eventually removed the pair.
