SAN DIEGO, Calif. – The San Diego Schools Police Officers Association is calling out the San Diego Unified School District for going back on its promise to transfer a student who injured a school police officer in February.

“We’re extremely disappointed in the way the school district is handling the discipline of a student who battered not just a school employee but a police officer,” union president Jesus Montana said. “The student should have been recommended for expulsion.”

Montana’s comments are in reference to a “play fight” that broke out during the lunch period at Lincoln High School Feb. 26. School resource officer Bashir Abdi followed one of the students into a parking garage, where an altercation occurred between the officer and several other students, NBC San Diego reports.

The incident was caught on surveillance video that has not been released to the public, but the students and officer were all taken to the hospital for injuries. The officer reportedly deployed his Taser and pepper spray on the students, who allegedly attacked Abdi and left him with a head injury.

Two students ultimately faced charges stemming from the attack, and yet one of them, Jesse Duncan, returned to Lincoln High School for the first day of school on Monday. Abdi, who sued his student attackers, is still recovering from his injuries, according to the news site.

“When the SDSPOA was informed late last week that the student, who injured a school police officer, would return to Lincoln High School, we were caught off guard and utterly disappointed. The disappointment stems from SDUSD turning their back on the students of Lincoln High School,” union officials said in a prepared statement cited by KGTV.

“In meetings with their student body leadership, district representatives, the School Police Department and our association, we all agreed we needed to work together to get past this. To do so we needed a fresh start, which included a new officer at Lincoln and all the participants that injured the police officer not return to the school.

“Respecting the wishes of the students and their desire to not only move forward but also rebuild the reputation of Lincoln High, the POA agreed to not fight the officer’s involuntary transfer. The district representatives also agreed to do their part by assuring the student would also not return.”

District officials, apparently, don’t see things the same way.

“There are people who think we should expel every student who makes a mistake. And, on the other side, there are people who want to remove all police officers from schools. My job as superintendent is to keep our students safe while giving them the best education possible, and accept that will not make everyone happy,” superintendent Cindy Marten said in a statement.

“Nothing is more important than keeping our students safe,” she said. “We are working with school police and the schools to ensure that the students and officers have what they need to work together in peace and have safe environments that result in successful outcomes for all parties involved.”

Montana said the district’s flip-flop on its agreement to transfer Duncan erodes the union’s working relationship with district officials.

“For the officers it’s a sense of betrayal, mistrust and not knowing if the district will have their back in the future if politics will lead the decision,” he said.

KPBS reported in March that Duncan is the son of San Diego rapper Brandon Duncan, also known as “Tiny Doo.”

According to the site:

Duncan made headlines in 2015 after he was jailed on a gang conspiracy charge over his rap lyrics. A judge tossed the case out. Duncan said he plans to meet with San Diego Unified Superintendent Cindy Marten to get his son cleared.
