Schools are taking precautionary measures amid a police investigation in Annapolis. Annapolis schools were under a precautionary “secure mode” for a time Wednesday as police investigated a report of shots fired near Tyler Heights Elementary School. The school was not involved in the incident, and city officials said there was no immediate threat to anyone at the school. Anne Arundel County Public Schools enacted the “secure mode” out of an abundance of caution, which meant no entry or exit from school buildings for the time being.
