The suspects took money and other personal property, including a laptop, from the students and then fled on foot.

The robbers are described as male blacks, 17-19 years of age, 5-feet, 9-inches to 6-feet, 4-inches tall and 140-175 pounds, medium-light complexion, with a short cut-dreadlocks hair style.

Three offenders wore black face masks covering the lower part of their faces.

“I am scared for my son, he has to go to school,” said the mother of one of the robbery victims, a 16-year-old boy. “They approached him. One pulled a gun, cocked the gun and told him, ‘You know what’s happening.’

“They started pushing and pulling him toward a gangway.”

He resisted, his mother said, and was punched in the face and had his laptop and other items stolen.
