Model and actor Ayyan was arrested at the Islamabad airport on Saturday allegedly for money laundering.
Ayyan was caught with $500,000 which she was allegedly smuggling to Dubai. The supermodel has been sent on a 14-day judicial remand to Adiala jail.
Ayyan was set to board an Emirates airline to Dubai without declaring to officials that she was carrying a large sum of money.
A money laundering case has been filed against her and she will soon be presented before a court.
Ayyan recently moved to Europe where she is working on taking up a new career in music.
