ALBUQUERQUE, N.M. — Classes are canceled for the day at an Albuquerque middle school that was evacuated because of what police say was an emailed threat.

Police announced Monday afternoon that Eisenhower Middle School has been cleared and nothing suspicious has been found.

Police say the emailed threat sent to law enforcement indicated there might be an explosive device or active shooter at the school.

The school district said earlier Monday the school was evacuated because of a bomb threat.

Police say they took into account weekend incidents that occurred in New York and Minnesota.

District spokeswoman Monica Armenta says officials decided to cancel classes after police said their investigation might take hours.

Armenta says all but a few of the school’s more than 800 students have been handed off to their parents.
