A Lehigh County man is facing assault and child endangerment charges for allegedly slamming his 8-month-old child against the wall and later assaulting the baby’s mother after babysitting for the night.

Allentown police charged Benjamin Ostrander with child endangerment, two counts of simple assault, two counts of harassment, criminal trespass and theft. Police arrested the 29-year-old on two sets of charges after officers were called early Friday morning to a South Third Street home to investigate an assault.

The first set of charges stems from an attack July 4 at the victim’s South Third Street home. She told police that a friend’s husband come to the house to retrieve his wife’s phone when Ostrander showed up.

Ostrander allegedly began yelling at the victim, slapped her, spit in her face and then grabbed the baby, throwing her against the wall. The child was taken to the hospital for medical evaluation; police said they observed a black-and-blue mark on her head.

Ostrander fled the home before police arrived.

Shortly before 1 a.m. Friday, police were called to the house because Ostrander had allegedly assaulted the girl’s mother.

The victim said Ostrander was babysitting while she was at work and initially refused to leave. He left, but came back a few hours later, kicked in the door and choked her. She told police that she feared she’d lose consciousness.

Ostrander allegedly stole her $700 smartphone.

Authorities arrested him at his mother’s Powder Mill Lane Road in Emmaus.
District Judge Michael D’Amore arraigned Ostrander Friday morning on both sets of charges, setting bail at a combined $100,000. He failed to post bail and was sent to Lehigh County Jail to await a preliminary hearing tentatively scheduled for Sept. 23.
