OAKLAND -- A North Oakland elementary school was locked down Friday after the family of one student received a threatening note from an acquaintance, school officials said.
The school district was able to get a stay away order served against the person on Friday and will lift the extra security precautions on Monday but maintain a heightened police presence, said Oakland Unified School District spokesman Troy Flint.
Access to Peralta Elementary School was restricted on Friday and there was security and police presence all day. He said the day "passed uneventfully."
The family of one student received threatening notes from someone they knew, with one note mentioning that the person knew the school their child attended, Flint said. He said Oakland police worked with San Francisco police on the stay away order but would provide no further details.
"We don't have any definitive information that there would be a definite action against the family," Flint said. "We are just being cautious."
The gates were locked throughout the day, beginning at 8:40 a.m., according to a letter sent to parents by Principal Rosette Costello. The gates reopened from 2:45 to 3 p.m. and Costello urged parents to pick up students promptly.
