Senior police have been forced to front the media and admit two officers stripped and ran around a police van at a set of traffic lights. And more naked police may have been inside the van, a senior official has admitted.



But they've stopped short of conceding the officers had attended a buck's party at Cleveland, on Brisbane's bayside.

"I believe it was some sort of pre-wedding party," Deputy Commissioner (Specialist Operations) Ian Stewart told reporters.

The police service's ethical standards unit is investigating allegations the two officers ran naked from a white Toyota HiAce stopped at the intersection of Moreton Bay and Redland Bay roads at Capalaba about 4.15pm on Sunday.

The van was believed to be en route from Cleveland to Oxley when the incident happened, sparking a complaint from a woman who reported seeing the naked men re-enter the vehicle after their run.
