ARLINGTON -- Rankin Elementary was placed on lockdown Wednesday morning because of a suspicious device found in a nearby dumpster, according to a school administrator.
Roads were blocked off and a few homes were evacuated in the area around the school, located in the 1900 block of Oleander Drive.
The lockdown was lifted before noon.
The Arlington Fire Department bomb squad responded with bomb-sniffing dogs and a bomb-detection robot. The device turned out to be a portable charger, used to jump start a car battery.
News helicopters hovered overhead as a robot and a fire fighter in a bomb suit approached the dumpster, where a custodian had spotted the yellow plastic case with jumper cables attached. The fire fighter retrieved the charger and gave the thumbs up.
By that time, dozens of worried parents had heard the commotion or received calls from AISD alerting them to an incident at the school.
Parents formed a long line to remove their children, despite the all clear. They said that in light of the Sandy Hook school shootings and Boston Marathon bombings, fear struck deep. They just needed to hold their kids.
The school's office manager told News 8's Cynthia Izaguirre all the students were safe, and if parents have questions, they can call the school.
Fire Lieutenant Kevin Seeton said the department responded with an abundance of caution.
