A group of about 20 migrants allegedly tried to enter a California school bus picking up students on Wednesday morning, district officials said.

The incident was one of two that occurred at a bus stop for Jamul-Dulzura Union School District students, with three men previously trying to enter the school bus on Tuesday, Fox 5 reports.

Superintendent Liz Bystedt said in a letter to parents that the group of migrants were walking in the middle of Highway 94 trying to stop one of the buses. 

Parents, however, were also at the site helping the bus driver ensure the students were safe and that none of the migrants boarded the vehicle. 

Nicole Cardinale, whose 8-year-old son was on the bus, told the outlet that it was “really scary” that the children had such an encounter.

“[My son] said these adults – they weren’t kids – had backpacks on and they were trying to get on [his bus]… He said there was a lot of them,” she said.

Additional details about the incident were not made available. 

The district did not immediately respond to The Post’s request for comment. 

The district has reported the case to the US Border Patrol, California Highway Patrol and San Diego County Sheriff’s Department. 

“We are conducting a follow up investigation to determine if a criminal act has occurred,” said Kimberly King, the media relations director for the sheriff’s department. 

“The Sheriff’s Office takes issues regarding student safety very seriously and are working with the school district in order to keep the students and our community safe,” King added. 

Bystedt said that as the investigation continues, all bus drivers have been instructed to skip over stops where migrants are nearby.  

“Please stay [vigilant] and if the bus drives by, please follow the bus to pick up your child at the next stop,” she told parents and guardians.
