A Long Island teenager was arrested Thursday and charged with vandalizing over a dozen homes and businesses with graffiti, according to Suffolk County police.

Christopher Lefever of Farmingville painted the graffiti tag "TUNAK" on 19 homes and buildings in his town over the past five months, police said.

Lefever, 17, of 23 Pleasant Place, was also charged with drug possession after officers found him with a small quantity of marijuana.

Suffolk County Sixth Precinct gang unit officers are asking anyone who has had their property vandalized with the graffiti tag "TUNAK" but who has not yet reported it to the police, to call them at 631-854-8671.
