The RCMP's anti-terrorism unit investigated a temporary federal employee arrested last May for allegedly leaking the Harper government's climate change plan, and passed the information on to Canada's spy agency, according to documents released through an Access to Information request.

The police investigation report into Jeff Monaghan, 28, is classified "secret" and dated June 2, 2007. It was obtained by Monaghan's lawyer, Yavar Hameed, after the Access to Information request was listed in an online database.

Monaghan, who was dismissed from his four-year temporary job at Environment Canada but never charged after the 2007 incident, said the investigation seems to have little connection with the leak that led to his arrest.

"Subject is a self described anarchist and drummer in a punk band that compares Harper to Hitler," the report's summary states. Monaghan's band, the Suicide Pilots, has a song called Harper Youth that refers to Prime Minister Stephen Harper while alluding to the Hitler youth movement in Nazi Germany.

The report includes drawings from the band's website.

"The logo for the band depicts a plane flying towards the Parliament Buildings as well, the website has a doctored picture of Prime Minister Stephen Harper pulling bombs and soldiers out of his pocket and throwing them to the ground," it states.

"Monaghan is also closely affiliated with an anarchist bookstore called Exile Infoshop (exilebooks.org), which uses the tagline "there's no government like no government."

Monaghan said his punk band tries to be provocative, but hardly warrants this type of anti-terrorism investigation by the RCMP.

"They were just kind concerned with isolating artwork that's deemed anti-statist or somewhat dissenting and running it through the national security network," he said.

He added that was definitely thumbing his nose at authority with the plane cartoon, but the drawing wasn't intended as a threat.

He wondered how many other small-time punk rockers with anarchist leanings might also be under similar investigation.

A news release issued by his band suggested that the investigation means the government may be monitoring other "dissenters that voice their politics through art."

"All art, all music, is threatened by such RCMP and CSIS monitoring," it said.

A spokesperson for the RCMP said the force will neither confirm nor deny the subject of any investigation.

Michel Juneau-Katsuya , a security expert and former CSIS agent, said he isn't surprised Monaghan's political beliefs were investigated.

"Here, we are trying to understand, from an investigator's point of view, what are the reasons for a person to break the trust and the confidence that was given to them," he said.

However, he said, it is somewhat unusual for the RCMP anti-terrorism unit to conduct the investigation.

RCMP officers arrested Monaghan and led him away in handcuffs from his office in Ottawa on May 9, 2007. They said it was related to allegations of breach of trust under the Criminal Code. Monaghan was accused of leaking details from a draft version of the government's regulatory framework for climate change.
