A 39-year-old Casino man may have thought he was helping police who wanted to search him for drugs by taking off his pants.
Instead he copped a charge of offensive conduct and obscene exposure.
Casino police allege they were called to the Casino train station last Tuesday at 7pm after reports a man was acting offensively at the station.
When police arrived the man immediately started abusing and swearing at police in front of nearby commuters.
Police informed the man that they intended to search him for drugs, but before a search could be carried out the man dropped his pants and made no effort to cover himself up.
He was placed under arrest and removed from the station.
Police said the man would face Casino Local Court in January to face the charges.
