The incident happened several months ago, according to a social media post Sunday from Alicia Martin.

Martin said she filed a police report against Creative Beginnings Daycare after finding the injuries and was told by an investigating officer that the bite marks were most likely from another child.

She’s warning other parents about taking their children to the nationwide chain.

“They did not even call when it occurred or notify me when I picked her up after work,” Martin said on social media. “All of these bites happened in one day.”

"At first, I was like 'are those really bite marks?' And then, my brain kinda stopped thinking and I started crying," Martin told KOLD-TV. "There's over 25 plus, it's hard to tell. Twenty-five would be the minimum that the police officer and I discussed."

Martin said she initially enrolled her daughter at the day care because it was accredited by the state and close to the University of Arizona where she attends classes.

Both the Tuscon Police Department and the Arizona Department of Health Services are investigating.
