ANTIOCH -- Three people were arrested after shots were fired near an elementary school on Wednesday morning, police said.

Officers were called to the area of F Street and W. 13th Street at 8:19 a.m. and found evidence of a shooting, Antioch police Sgt. Santiago Castillo said. No injuries were reported. The address is adjacent to Fremont Elementary School, which begins classes at 8 a.m.

Witnesses helped direct police to the 500 block of W. 14th Street, where a suspect in the shooting had fled into a house, Brooks said. Six people were at the house when police arrived, Brooks said, and three of them were led out in handcuffs.

The three were arrested on suspicion of narcotics and weapons violations, vehicle theft and possession of stolen property, Brooks said. Witnesses also identified one of the three as the suspected shooter, and the gun believed used in the morning shooting was taken from the house, Brooks said.

Teachers and staff at the Fremont Elementary notified the Antioch School District around 8:15 a.m. that they had heard shots outside the school, and the campus was immediately locked down by Principal Heather Ogden, said Bob Sanchez, the district's director of student services.

"At no time were the staff and the students in any danger," he said.

Police gave the school notice around 9 a.m. that the arrests were made and that the campus could lift the lockdown, Sanchez said.

None of the three who were arrested have been identified; police cited the ongoing investigation for not doing so.

Police were still seeking witnesses to the shooting and urged anyone with information to call 925-778-2441 or text anonymously to 274637.
