State Police say a multi-agency task force arrested Amin and two other people at a Summersville residence after receiving a tip from an informant. A search found oxycodone pills, heroin and $3,000 in cash.
Another cast mate, Michael Douglas Burford, was charged in February with driving under the influence.
Urbanski said none of Gandee's cast mates was available to do an interview Monday, and none immediately planned to issue a statement. But their feelings came through on Twitter, where Ashley Whitt called her friend "the most amazing person I've ever known."
"I know you will be watching over me every time I hit a mudhole. You will always be my best friend, I love you!" she wrote.
Cast mate Cara Parrish and others asked fans to pray for Gandee's parents, Loretta and Dale. "This is the emptiest I've ever felt," she wrote in a tweet.
