Sources tell News 12 that at least four more teens are in custody in connection to the Oceanside stabbing that killed 16-year-old Khaseen Morris last week.

Nassau County police and homicide detectives pulled over cars Friday morning in Long Beach and were also seen at a house on East Fulton street.

It's the same house featured in a video made by 18-year-old Tyler Flach of Lido Beach, who was arraigned on a second-degree murder charge in the case.

Police say Flach plunged a knife into Morris during the after-school brawl that was caught on cellphone camera.

Officials say they identified seven teens seen with Flach the night of the fatal brawl.

Sources also say that at least four of the teens that are in custody will be arraigned on Saturday.

A funeral will be held for Khaseen Morris on Saturday at Towers Funeral Home in Oceanside
