PLANO -- The Plano Independent School District says two schools are no longer in lock out mode over police activity in a nearby neighborhood.

Parents of students at Armstrong Middle School and Forman Elementary School were alerted at about noon Monday, a spokesperson told WFAA.

The lock out was lifted before 1 p.m.

Plano PD tells WFAA that the activity stemmed from a welfare check at an apartment complex nearby and involved the search for residential burglary suspects. They have since been arrested.
