Century High School in Sykesville was evacuated Tuesday afternoon after threatening graffiti was written on a bathroom wall, Carroll County school officials said.
An Alert Now electronic message sent out by the school system about 2 p.m. said that law enforcement officials conducted a "comprehensive" search of the school and found "no threat or danger." Students and staff re-entered the building, the message said.
The incident came a day after graffiti was found on a bathroom wall at Sykesville Middle School that indicated a threat to the building, according to another Alert Now electronic message from the school system. The school administration was alerted to the graffiti after students had been dismissed Monday, the message said, and a search by law enforcement found no danger.
The school system has now dealt with three threats in the past several weeks. A bomb threat was written on a wall at Liberty High School on Nov. 20, prompting an evacuation of that school. The county sheriff's office and explosive detection canine units searched the premises, but nothing was found and the school was reopened.
