Allison Nagel, 23, of the 500 block of Hancock St., was charged with child endangering.
A passerby called police at about 10 a.m. after he saw Nagel repeatedly hitting and biting her boyfriend while they walked down Hancock Street, according to a police report.
Nagel got mad because her boyfriend said he was going back to school rather than taking on a second job, the report said. Nagel then allegedly hit the man, who picked up their son and began walking away. Nagel continued her onslaught as the 1-year-old child was still in the man’s arms, the report said. The man showed officers three fresh bite marks, allegedly inflicted by Nagel.
Further charges could follow, police said.
