Investigators said a customer reported a man inside the Big 5 Sporting Good Store comment to an employee that he wanted to buy a gun. Then, the man allegedly threatened to shoot up a school and asked an employee for a good shirt to wear.
San Mateo police arrived at the store within minutes and searched for the man, but they couldn't find him.
Police released surveillance video Monday showing the man attempting to buy a gun inside the store. Big 5 employees did not sell him a gun and asked him to leave.

Witnesses told police no specific school was named and they did not believe the threat was credible. He's described as a white man, possibly transient, about 35 years old, wearing a camo sweatshirt and blue jeans.
Over the weekend, schools in San Mateo were notified about the incident. "We are just making sure all our staff and parents know that we are more vigilant and more aware today, making sure all gates and doors are locked," San Mateo Foster City School District spokesperson Amber Farinha said.
A San Mateo Unified High School District spokesperson says they will not be on lockdown, but are asking campuses to be on heightened awareness. Police officers and staff will provide extra eyes on campus.
All of this is making some parents and students anxious. "I didn't tell my little one anything about it because he would have panicked. He was scared. He was like 'I don't want to go to school mom. I don't want to go to school. What if I die? What if I die?' That's all he could think of," parent Sonia Green said.
As a result of the threat, Saint Gregory Catholic School Principal Laura Miller, said her school will be taking extreme precaution and following suit to the San Mateo public schools and shelter-in-place all day Monday.
She sent out a message to parents telling them students will not be switching classes and classroom doors will remain locked. Students will eat lunch and have recess in their classrooms.
San Mateo police said even though witnesses say the threat did not seem credible, they still want to talk with him themselves to make their own conclusion.
