BRUNSWICK, Ga. -

Three of four teenagers charged in connection with sucker-punching another teen inside a Brunswick Walmart remain in jail.

Judge Timothy Barton set a $2,500 bail Friday morning for 18-year-old Jervon Sanderson, one of the four arrested Thursday for what Glynn County police said was their involvement in the "knockout game," in which offenders try to knock someone unconscious with a single blow. Sanderson was later released on bond.

Kaleb Dirting, 18, also appeared before Judge Barton on Friday but was denied bond. The District Attorney's Office didn't provide details as to why one teen was granted bond and another wasn't, saying in a statement, "The two teenagers who appeared before the judge this morning had varying levels of participation in the case."

The other two teenagers arrested -- Brandon Allen Jr., 18, and Ramone Roberson, 19, did not appear in court Friday, though it's unclear why.

According to police, Allen punched the 16-year-old victim during the incident caught on surveillance video early Sunday morning. He and Roberson also remain in jail.

No one was at Allen's home Friday.

Dirting, Allen and Sanderson will all have their next court appearance March 7.

Roberson's uncle said Roberson and Dirting are seniors at Glynn Academy, while Sanderson attends Brunswick High School. He wasn't sure about Allen.

Neither school commented Friday.
