A two-month investigation led to the arrest over the weekend of a New York man and to the seizure of $42,411 worth of untaxed cigarettes, according to the Maryland comptroller's office.
Ahmed Oman Mohammed, 32, was arrested by enforcement agents for the comptroller's office after his van - which authorities said contained 12,900 packs of untaxed cigarettes - was stopped early Saturday on Route 301 and Old Marlboro Pike in Prince George's County.
Mohammed was charged with transportation of untaxed cigarettes, a felony that carries a sentence of up to two years in prison and a fine of $50 per carton.
Maryland officials said that the cigarettes were purchased in Virginia and illegally transported into the state. They said it was not clear where they were to be sold.
Cigarette smuggling has been a growing concern in Maryland since legislators raised the state's tax on cigarettes last year.
