CAMDENTON -- Camdenton County police arrested four men on first degree robbery charges.

Authorities said Jacob Strickland, 18, of Tunas reported he'd been robbed at gunpoint by three men.

Officers arrested three suspects shortly after the incident last night, Evon Smith, 18, of Maryland Heights, Michael Tate, 19, of St.Louis and Labyron Jackson, 18, of St. Pierre, Il.

Those suspects implicated a fourth man, Ryan Vansyoc, 18, of Camdenton.

Police said Vansyoc put the other subjects in contact with the victim to purchase drugs.

Strickland is charged with possession of a controlled substance with intention to distribute.
