AUGUSTA (AP) — An Augusta man has been charged for allegedly striking a 4-year-old girl he was supposed to be caring for and holding a blanket to her throat so tightly that it left marks.

Brent Ryan Lavallee was ordered held on $5,000 cash bail at a hearing Tuesday in Kennebec County Superior Court on a charge of felony assault.

Police say the 28-year-old Lavallee was taking care of the girl last Thursday when he struck her and gave her a black eye, and left marks on her neck.

He was arrested Friday after the girl’s grandfather noticed the injuries and alerted police.

The Kennebec Journal reports that police think Lavallee was angry because the girl would not go to sleep.
