Seven more teenagers were arrested on Friday for their roles in the stabbing death of a Nassau County high school student earlier this month, authorities said.

In previous reports, 18-year old Tyler Flach was charged with second-degree murder of 16-year old Khaseen Morris, now 7 additional teens have charges associated to his death.

According to New York Post, the suspects — 19-year-old Haakim Mechan; 18-year-old Marquis Stephens; 18-year-old Javonte Neals; 17-year-old Taj Woodruff; 17-year-old Sean Merritt and two younger teens who were not named — were all hit with gang assault charges in the slaying.

Khaseen Morris was stabbed once in the chest near a strip mall by his high school after being attacked by a group of teens in an apparent beef over a girl on Sept. 16, police said.

As he suffered from the stab wound, teens recorded him with their cellphones instead of offering help, police said at the time.

Two days after the attack, police arrested Tyler Flach and charged him with murder, authorities said.

After the slaying, police said they were searching for six to seven other teens in the attack after interviewing witnesses and reviewing footage posted on social media, including on Snapchat.

They’re all now in custody.
