UPDATE: Sioux Falls police arrested the unauthorized man spotted at two schools

SIOUX FALLS, S.D. (Dakota News Now) - A letter from the Sioux Falls School District reported staff witnessed an unauthorized man performing suspicious behavior at two Sioux Falls schools.

Update @ 2:40 p.m.: According to the Sioux Falls Police Department, the report of the suspicious person came from the school Laura B. Anderson on Friday, Aug. 26. Around 7:20 a.m., a man was on the school grounds and was trying to get a child to go with him. A staff member saw the unusual behavior and confronted the man, who then left the school property. This was reported to the police, but the officers were unable to find the man.

On Friday afternoon, around 1:20 p.m., a man was approaching children outside Saint Mary’s. He was also confronted by staff and left school property.

As school resource officers investigated these two cases, it was determined that the same person was at the two schools trying to entice children to go with him. The suspect was found on Monday at 1:20 p.m. in central Sioux Falls and arrested without incident.

The suspect is Anthony Vincent Lewis, a 54-year-old man from Springfield, SD. Lewis was arrested for Enticing a child under 14, Kidnapping, and Contributing to the delinquency of a minor.

Update at 2:25 p.m.: The School Falls School District said police have located the unauthorized man, and officers are “handling the matter.”

Previously: The Sioux Falls Police Department has been notified after a staff member reported seeing the suspect talk to a child. The staff member was able to intervene, and the man left shortly after. The same suspect was later reported at a private school several miles away.

According to the letter, police know who the suspect is and are working to locate him. School staff has been notified to be aware of the suspect, and authorities would like parents to remind their children not to talk to strangers.

“The safety of our students and staff is our highest priority. Please ensure your child has a safe route to school. Students should always walk with others and avoid talking with strangers. Children should be reminded to ‘See Something, Say Something’ if they are approached or feel uncomfortable with any situation,” the letter says.
