A 22-year-old Bonner Springs man has pleaded guilty to two counts of attempted robbery in connection with the robbery of four Kansas University students outside a Lawrence Burger King.

Antoine Barber pleaded guilty to the two charges earlier this month. Prosecutors originally had charged him with four counts of aggravated robbery in connection with the January robbery, according to court records.

District Chief Judge Robert Fairchild on Monday delayed a preliminary hearing until June for Barber’s co-defendant, Nicholas G. White, 20, of Kansas City, Kan. White faces four aggravated robbery charges in the case, and Barber is listed as a potential witness, according to court records.

The two men are accused of demanding cash at gunpoint from four KU students early the morning of Jan. 25 as the students were waiting for food in the drive-through lane at the restaurant near Sixth and Missouri streets.

Fairchild is scheduled to sentence Barber on April 28. Both Barber and White are free on bond.
