Lancaster police say 42-year-old Rex Mettler is charged with felony menacing by stalking. Police say he made violent threats against 19-year-old Alyson Michalka and her 17-year-old sister Amanda.

Aly starred in the Disney Channel series “Phil of the Future.” Both appeared in the Disney Channel’s 2006 movie “Cow Belles.”

No attorney is listed for Mettler. He is scheduled to be arraigned Friday in Fairfield County Municipal Court.

A message left with a Disney spokeswoman wasn’t immediately returned Thursday.

Aly and AJ are scheduled to perform Friday night at National City Pavilion in Cincinnati.
