A report of a man with a gun on campus prompted the evacuation of La Escuelita Elementary School in Oakland this afternoon.
Officers responded to the school, located at 1100 Third Ave., after receiving the anonymous tip at 12:45 p.m., a school district spokesman said.
"A man said he witnessed another man enter campus with a rifle and go into one of the buildings," Oakland Unified School District spokesman Troy Flint said.
He said the school was initially put into lockdown, and has since been evacuated. Students were taken to a safe area and were to be reunited with their parents once everyone was accounted for.
Parents were asked to pick up their children at the Peralta Community College District at 333 E. Eighth St.
There are no reports of injuries.
"All the children are safe and accounted for," Flint said.
Dozens of parents had gathered at the pickup location as of 3 p.m., anxiously waiting for their children as news helicopters hovered overhead. Some were crying, even as police reassured them that their kids were safe.
"I heard the police say it's OK but I saw the helicopters - I didn't know what happened," said Kathy, the mother of a fourth-grader who declined to give her last name.
Susanna Huerta, whose 7-year-old son Brian is in the second grade at La Escuelita, said she had gotten a phone call from the school.
"The school forwarded a voice mail to inform me they were safe but I'm a little nervous until I see him," she said.
One parent, Jabari Shaw, was particularly antsy.
"Give me a vest and I'll go in there and get them myself," he said.
Shaw's nephew and 3-year-old son attend the nearby Laney College Child Care Center, which he said was also evacuated.
Venissa Barrun, the mother of a third-grader and a fourth-grader at La Escuelita, said she is raising her kids on her own because her boyfriend is in Iraq.
"I don't know what's worse, them being here or my boyfriend being in Iraq," she said. "I don't expect this to happen at home."
Flint said the report of a gunman has not been verified.
