Three Waialua men were arrested early yesterday on suspicion of firearm and drug-related offenses after a traffic stop on California Avenue in Wahiawa.

The Honolulu Police Department's career criminal unit is investigating the case, which may be turned over to federal authorities because of the "dealer amount" of crystal methamphetamine involved. The men ­ ages 20, 19 and 18 ­ are in custody but have not been charged.

The men were in a truck with oversized tires that was stopped by a patrol officer on California Avenue on suspicion of a possible reconstruction violation. While the officer checked for a reconstruction permit, he observed two boxes of ammunition, a handgun and a large packet of what appeared to be crystal methamphetamine in the truck.

The career criminal unit is handling the investigation.
