A 26-year-old French tourist will head home from Brisbane after being spared further jail time for what has been described as a "bizarre series of offences".

Mickael Massiera was on a working holiday when his lawyer said he went off the rails.

The District Court heard he resisted arrest after being caught with cannabis late last year.

His behaviour deteriorated at the watch-house, with Massiera smearing faeces on walls, obscuring a CCTV camera an eventually biting a civilian officer with force on the calf.

The officer went to hospital and endured stress as a result.

Massiera has spent 100 days in jail already and today's sentence did not impose further time.

He will be on a flight to France next week.
