A precautionary lockdown placed at Valley Center Middle School has been lifted, the school said.
The school was placed on lockdown as the San Diego Sheriff's Department checked a nearby house on North Lake Wohlford Road for reported domestic violence and a bomb threat.
The California Highway Patrol created a perimeter around the school and casino while they investigated the incident.
The man, who appeared intoxicated, said there were were several bombs and devices placed in or around the home, deputies said.
Deputies froze at the scene and the Sheriff's bomb squad responded, checking for explosives on the property. They found nothing and took the man into custody.
Students at the middle school were dismissed as usual at 2:45 p.m., and all after school sports were canceled on Tuesday.
"Many thanks to the San Diego Sheriff's deputies and detectives for their support today, and to our staff and students for a job well done," the school said on its website.
