MONROE - A Monroe man was arrested for cocaine possession after the State Line Area Narcotics Task Force executed a search warrant at a residence on 16th Avenue Monday. Monroe High School and Abraham Lincoln Accelerated Learning Academy were put on lockdown for about 20 minutes during the search. School doors were locked and students and staff remained in classrooms while police were searching the residence, but District Administrator Cory Hirsbrunner said the lockdown was a precaution and the schools were never in any immediate danger.
