Police were searching Saturday for a man who wore a ski mask and wielded a rifle while robbing a convenience store Friday in north Orem.

Police said a young man had been playing video games at the 7-Eleven, 794 N. State St., but left the store just after 1 a.m. A person identified by store employees as the same young man returned a few minutes later wearing a green ski mask and carrying a .22 caliber rifle with a scope.
