SELBYVILLE, Del. – A mom in Delaware has been arrested after her 4-year-old daughter brought heroin to school, thinking it was candy.

Delaware State Police said the girl gave it to her classmates.

Ashley Tull, 30, was charged with maintaining a drug property and three counts of endangering the welfare of a child.

Authorities told WTXF that troopers and medical personnel responded to the daycare shortly before noon Monday after workers saw some of the children with small bags of an unknown substance.

Officials tested the substance to confirm it was heroin.

Police said the girl inadvertently brought the bags of heroin in a backpack that Tull had given her after the girl’s regular backpack was ruined by a family pet Sunday night, according to police.

Authorities said the child thought the packets were candy and began passing them out to other students

Several children were taken to area hospitals as a precautionary measure and were released.

Officials found a total of 249 bags of heroin weighing 3.735 grams in the backpack, according to Delaware State Police.

Police said a 9-year-old boy and an 11-year-old girl also live with Tull in addition to the 4-year-old girl.

She was released on $6,000 bail.

Authorities said a no-contact order was issued and the children are currently in the custody of a relative.
