Police are seeking a trio of teens possibly connected to a group beating that left a 17-year-old girl dead.

Tajae Warner, 17, died in Bellevue Hospital on Tuesday night from injuries sustained when four teenagers, one of whom is in custody, allegedly beat her on Saturday for defending her younger brother when he was taunted, Pix11 reported.

Prosecutors told the New York Daily News that the fatal assault happened near Coney Island’s Ocean Towers on West 24th Street. Warner was going with her 11-year-old brother to the store when the group of teens allegedly made a remark before assaulting her.

The group, comprised of two boys and two girls, allegedly threw Warner to the ground and punched and kicked her, Pix11. It is believed that Warner’s head hitting the pavement caused her to become unconscious.

Sarina Agard-Forde, 18, was arrested and will face an attempted murder charge, police said to Pix11, adding that the other three teens allegedly involved were still being sought.

Warner’s father said to Pix11 that his daughter’s attackers should give themselves up because “the one that they do have in custody will sing. She's going to sing her tune."

Authorities are investigating area surveillance cameras that may have recorded images of the attackers, Pix11 added.
