A 29-year-old motorist accused of fatally mowing down a Brooklyn boy on his bicycle had previously lost his license and never applied for a new one, court papers show.

Victor Mejia was arrested Saturday morning after he struck 10-year-old Dalerjon Shahobiddinov while the boy rode with the light in the crosswalk on Foster Avenue in Kensington around 10:30 a.m., according to police.

The unlicensed driver had turned left in his 2002 Ford Explorer onto Foster Avenue after the light turned green on Seton Place when he felt a bump, according to a criminal complaint.

Mejia “got out, and then the defendant saw Dalerjon Shahobiddinov in the roadway and that Shahobiddinov’s bicycle was underneath the defendant’s vehicle,” court papers said.

Cops took Majia into custody at the scene.

According to court papers, his license was previously suspended, and he never paid to have it reinstated. It wasn’t clear why his license was suspended.

Mejia appeared in court in Brooklyn on Sunday and was released without bail on charges including failing to exercise due care while driving and aggravated unlicensed operation of a motor vehicle. He is next due in court Nov. 4.
