U.S. authorities have arrested a suspect who masterminded the shooting at a shopping mall in Washington, which led to the death of five persons.

Turkish-born, Arcan Cetin, a 20-year-old resident of the nearby town of Oak Harbor, according to the police was arrested on Saturday.

However, the FBI has said there was no evidence yet that the shooting was terrorism related.

Cetin had opened fire on fire on shoppers in the mall, killing four women and a man and then left the store on foot.
