"This is just bullshit!" Leonhart waved his hand and rebuked. 

"Don't you know that your little brother is still young? Why do you let him do such a naive move? The cruise ships around the pier were where all the big family ships gathered and the surveillance was very tight. Does your brother think that the Graham family won't find his trick? Now, not only Luke does not want to let go, even the Grahams also rushed to intervene and asked Lyle to give an explanation."

Because of this, Leonhart let Lyle stay in the police station for a while.

This problem involves important figures that had been targeting Leonhart. The main family were like wolves, and now the Grahams were out to testify against Lyle. So of course this matter wasn't easy to solve.
