Brussels Bomber Caught in Turkey in 2015

One of the suspected airport terrorists in Brussels was reportedly detained last year in Turkey. According to The Guardian, alleged suicide attacker Ibrahim el-Bakraoui wasn't arrested in 2015 based on a specific threat but rather on suspicions that he was tied to foreign terror organizations. El-Bakraoui was deported to the Netherlands after his arrest, and while he was not known to Belgian authorities they were reportedly made aware of his previous run-in with authorities.
