An unruly pub patron and his two guinea pigs were detained by police after “one of the more bizarre” incidents a regional Queensland officer has encountered.

Senior Constable Mick Bleakley said he initially doubted the story when he was called out to deal with a drunken man who turned up at a Hervey Bay hotel on Thursday night with pet guinea pigs.

Bay Central Tavern patrons became concerned at the man’s “unusual and disorderly behaviour”, noticing he had two guinea pigs squashed into a 600mL Breaka milk carton, Senior Constable Bleakley said.

The man reportedly patted the guinea pigs in the container while in the tavern.
