The four hooligans who ruthlessly bullied school bus monitor Karen Klein have officially been served their punishment -- and it's a big, fat suspension.
In a statement released by the Greece Central School District ... the four seventh grade boys who taunted the 68-year-old grandmother were issued a one year suspension from school, a one year suspension from bus use, ordered to perform 50 hours of community service with the elderly and are required to participate in a bully prevention program.
The district added that the boys will be sent to the district Reengagement Center -- a special alternative education program -- since by the law they are required to provide an education.
If you recall ... Klein's story received national attention after a 10 minute YouTube video of the boys bullying her on the bus went viral. She has said from the beginning she did not want to press criminal charges.
