A man has been charged with attempted arson over an attack on a Brisbane city councillor's office.

The 41-year-old man allegedly set a truck tyre on fire and wheeled it into Councillor Ryan Murphy's office at Cannon Hill on Brisbane's eastside this morning.

He was arrested and taken to hospital after being bitten on the bottom by a police dog.

The man has also accused of injuring the dog and seriously assaulting an officer.

Senior Sergeant Murray Crone says police were patrolling the area.

"There were flames coming from the Council office," he said.

"The exact motive for this offence is unknown at this time, however detectives are making further investigations."

Councillor Murphy says he is shocked by the incident and he is not aware of any motive for the attack.

"Really shocked - I think any councillor whose office attempted to be burnt down would be," he said.

"But really at this stage we just want to wait and see what the result of the investigation is."

Councillor Ryan Murphy says there was only minor damage to the office.

"This person for whatever reason has set out to do some damage," he said.

"You don't use a truck tyre to start a fire unless you want to do some serious damage, but obviously we've got to let [police] complete their investigation.

"The office is still a crime scene at this stage."
