One day after being arraigned on sexual assault charges, Bill Cosby has finally broken his public silence on the accusations against him. "Friends and fans, Thank You," the 78-year-old comedian wrote in a tweet on Thursday.

People reported Wednesday that Cosby was charged with felony aggravated indecent assault stemming from a 2004 incident in which he allegedly drugged and sexually assaulted former Temple University employee Andrea Constand at his Pennsylvania mansion.

"Obviously we appreciate the expression of confidence in her," Constand's attorney, Dolores Troiani, told the publication about the decision of issuing a warrant. "We'll have to see what happens. We hope justice will be done. We will cooperate fully."

Cosby was arraigned in Pennsylvania's Montgomery County District Court on Wednesday and released after posting $1 million bail.

"Let's all stay classy plz!" Constand tweeted on Thursday. "That includes anybody who may be inserting their opinion as to whether anything was fully investigated period."
