Many Nelson Mandela High School students returned to class Friday following a two-day boycott over security concerns.

Parents encouraged the boycott, which took place after they say the school cut down on the number of security guards from 13 to five. School officials say they have one less guard this year, saying the school has six security guards for the school?s 180 students.

?Nelson Mandela has the highest ratio of security officers - one safety officer to every 30 students,? says Maureen Gonzalez, the deputy school superintendent.

Just 40 students went to class Wednesday and only 25 went Thursday. School officials say 111 students showed up Friday.

Concerned parents say they worry about the safety of their kids at the school with the reduced number of guards.

?The city is going to be set up again for a lawsuit,? says Hammurabi Bey, a parent. ?The first thing that happens at the school, the parent will take this district to court.?
