OAKLAND (CBS/AP) — Oakland Unified School District, which fired a high school security officer last week after surveillance video showed him attacking a handcuffed student in a wheelchair, has released a second video showing more details of the incident.

The two-minute video released Tuesday by Oakland Unified School District spokesman Troy Flint appears to show Oakland High security guard Marchell Mitchell first dumping student Francisco Martinez out of his wheelchair, then kicking him and dragging him into an elevator.

The second guard was identified as Shalandra Cotton and, according to Flint, the district has put her on paid administrative leave as of Wednesday while the incident is being investigated.

Attempts to reach Cotton for comment were not immediately successful.

The incident in the newly-released video precedes the video that Oakland Unified released last week, which showed Mitchell slapping Martinez and dumping him out of his wheelchair.

As it happens, both Mitchell and Cotton took a class on conflict management in April.
