An Industry man accused of assaulting his child’s mother while the infant was in the car last week remains in the Butler County Jail Wednesday waiting to find out if he’ll be released.

Thomas Elko, 28, is facing charges of reckless endangerment, endangering the welfare of a child, simple assault and drunken driving.

According to police, Elko was driving his 1-year-old son and the child’s mother, Jessica Freeman, on Route 51 on June 20 when he began assaulting Freeman.

Authorities said Elko was driving nearly 100 mph during the incident.

Freeman told police that Elko would erratically slam on the brakes so her head would hit the windshield.

Officials said Elko eventually pulled over in the parking lot of Pier 19 on Bridge Street and let Freeman out of the car. She said she tried to take the child with her, but Elko wouldn’t allow it.

Authorities caught up with Elko a short time later and stopped hime because they said he was speeding and swerving in-and-out of traffic.

Officials have not released the results of Elko’s blood-alcohol test, but police said he smelled of alcohol at the time of the arrest.

“It never should have happened, that’s all,” Elko’s father said Wednesday.

Elko waived his right to a preliminary hearing on Tuesday.
