When a mother picked up her 15-month-old daughter from preschool, she was horrified to find 25 bite marks on her back.

Alice Martin, from Arizona, had signed up her toddler for daycare at Creative Beginnings Daycare in Tucson. Just five days later, the incident took place.

Now, Alice is accusing the preschool of negligence and reported the ordeal to the police department as well as to the Department of Health.

“It’s stomach-turning,” Martin told KOLD News 13. “It feels both angry and sad at the same time. At first, I was like ‘are those really bite marks?’ And then, my brain kinda stopped thinking and I started crying.”

“The fact they didn’t notify me even when I picked her up is just astounding. I know that a child getting bitten that many times would be crying and very upset. You always want to protect your children and I feel like that didn’t happen. I feel like I left her with someone that didn’t look out for her at all.”

Martin also went on Facebook to share pictures of the bite marks. As of the time that this is being written, more than 12,000 people have shared the pictures with others and many comments are coming from people who are absolutely outraged.

An investigating officer told Martin that the bite marks were more than likely from another child. As of now, no arrests have been made.

A statement has not yet been released by Creative Beginnings Day Care about the incident. According to a spokesperson for the Department of Health, no comment was available because of the ongoing investigation.

“The fact that nobody intervened in how many minutes, maybe they were left alone, maybe they disregarded the cries, I don’t know, but it takes some time to do that kind of biting and my daughter would have been very upset,” Martin added.
