Police are planning to apply for an arrest warrant for the mother of the 4-year-old boy who had brought nine bags of marijuana to school on Tuesday and offered them to classmates during snack time.

Sgt. Darrin McKay of Connecticut said that the investigation by the Meriden Police and the Department of Children and Families is still open, and that officers in charge of the case will be applying for an arrest warrant for the mother of the child, according to a report by the Meriden Record-Journal.

Meriden Police would charge the mother with risk of injury to a child, possession of a controlled substance and intent to sell, McKay said.

Detective Lt. Mark Walerysiak told Meriden Record-Journal that police don’t want to rush the investigation.

"They wanted to make sure they knew where the marijuana came from," Walerysiak said. "You don't want to rush and put a case that may have holes in it through the courts. Sometimes it's smarter to step back and do a little more digging before making an arrest. That's true of any case, not just this one."

Hanover Elementary School Superintendent Mark Benigni said in a press conference the investigation centers around the wellbeing of the 4-year-old.

"Our concern is for the 4-year-old student, who had no knowledge of what he was bringing to school," Benigni told reporters.

On Tuesday, police said that the teacher had called the principal who in turn called the police after seeing the student take out marijuana that was inside bags that appeared to be wrapped in preparation for sale, the Meriden Record-Journal reported.
