MEMPHIS, Tenn. — Police say two students have been taken into custody after two chemical-filled bottles exploded at a Memphis high school.

Memphis police said in a news release Thursday night that two 18-year-old students of Craigmont High School were charged with aggravated assault, felony reckless endangerment and possession of a prohibited weapon.

The high school was evacuated just before noon in what school authorities called a prank explosion. Officials say an assistant principal with asthma went to the hospital after inhaling smoke produced by the mixture. Police said a bomb threat had been called in to the school beforehand.

Shortly after, another bottle exploded about 15 miles away outside a Kroger grocery store. Kroger spokesman Joe Bell says a customer accidentally left behind a bottle with dry ice. No one was injured.
