Authorities are investigating a two-vehicle accident involving a police car and a school bus filled with middle school students in McAllen.
The accident happened off South 2nd Street and the frontage road of Expressway 83 in McAllen just before 3 p.m. Thursday.
McAllen police are investigating the accident between an Edinburg CISD school bus and an Edinburg CISD Police Department squad car.
Edinburg CISD officials confirmed that the bus was carrying students from Barrientes Middle School.
The students had gone to the State Farm Arena in Hidalgo on a field trip to the Rio Grande Vipers play a game as a reward for perfect attendance.
Edinburg CISD Police Chief Rick Perez said the school bus and the police car were part of a convoy and returning back to Edinburg at the time of the accident.
Chief Perez said the police officer was trying to pass the bus to block traffic for the convoy when he looked down to flip the controls for his overhead lights.
The officer's patrol unit clipped the rear bumper of the bus causing minor damage.
Chief Perez said the officer has been with the school district for several years and was not hurt in the accident but an administrative investigation will take place.
Although no students were reported as injured, five of them were taken to a local hospital for evaluation.
Edinburg CISD spokesman Gilbert Tagle said the remaining students would be evaluated by a school nurse upon their return to campus.
Tagle said that as per school district policy, both the school driver and the officer are both requiered to undergo drug testing.
