( CNN ) -- Rather than a bagged lunch , a Pennsylvania first-grader brought bags of heroin into school -- giving some to at least one classmate before teachers caught him with a pocket full of drugs , authorities say . Two days later , the boy 's 56-year-old grandmother was arrested on charges of endangering the welfare of children and drug offenses for allegedly losing track of the heroin while babysitting , according to a local district attorney 's office . Chester County , Pennsylvania , District Attorney Tom Hogan expressed outrage over any child bringing a drug as potent as heroin into an elementary school . He also lashed out at the boy 's school district for not doing more to inform parents as well as authorities , including his office . `` Any exposure to heroin for a young child is likely to result in death , '' Hogan said in a statement released Monday . `` The ( grandmother ) is lucky that she was not responsible for the death of her own grandson or somebody else 's child . '' According to a criminal complaint detailed by Hogan 's office , Pauline Bilinski-Munion was babysitting her grandson and a 1-year-old baby last Thursday at a residence in Modena , Pennsylvania . Bilinski-Munion had `` brought heroin into the house and lost track of it , '' according to the district attorney 's office , which referred to her as `` a known heroin user . '' The next day , the 7-year-old brought several bags of heroin with him into Caln Elementary School . Teachers overheard the child talking about the bags , and later found nine bags of what proved to be heroin -- with each bag stamped , `` Victoria 's Secret '' -- in the boy 's pants pocket , the prosecutor 's office said . The child initially claimed he found the heroin in the school yard , only to later admit he 'd gotten them from home . The drugs were then handed over to the Coatesville Area School District Police . Another child 's mother later claimed that she 'd found an additional bag of heroin , with the same `` Victoria 's Secret '' wording , on her 7-year-old as they were walking late Friday afternoon in a nearby mall , authorities said . What happened next is a matter of dispute . The school district did n't respond to repeated CNN calls for comment . But CNN affiliate KYW reported that , in a statement , the district `` immediately contacted Caln Township , Coatesville city and ( the ) South Coatesville Police Departments . '' Yet Hogan faulted the school system for what he characterized as its `` late and vague notification to parents about a 'dangerous and illegal ' substance , '' and failing to alert his office , which did n't start investigating until hearing about the story in the media on Saturday . `` The school district did n't call 911 , did n't call the DA 's office , did not freeze all the kids in place , they did not call in emergency personnel to check all the kids to make sure they were OK , '' he told KYW . `` They did not check to see if there was heroin anywhere else around . '' Following her arrest Sunday , Bilinski-Munion was charged and held with bail set at $ 25,000 . Efforts by CNN to reach her relatives have been unsuccessful , and it was n't immediately known who is representing her in court .
