Linyorth S. Siu-Jackson, 24, of Beach Park.

A Beach Park man is being held on a $350,000 bond after police say he struck a baby several times, injuring it, because the child woke up during the night crying.

Linyorth S. Siu-Jackson, 24, of the 39000 block of North Sheridan Road in Beach Park, was charged with aggravated battery to a child causing great bodily harm and harassment through electronic communication.

Lake County Sheriff’s Office Deputy Chief Christopher Covelli said detectives took a report of a battery to a child that occurred during the Fourth of July weekend.

The complainant is the mother of a 9-month-old boy.

The woman reported that her relative, Siu-Jackson, was babysitting the 9-month-old overnight during the Fourth of July weekend.

Siu-Jackson allegedly struck the baby on the back several times, causing injuries, after the child woke up in the middle of the night crying, Covelli said.

Covelli said that Siu-Jackson was additionally charged after he threatened to cause bodily harm to the mother’s family via electronic message.

Siu-Jackson remains held in the Lake County Jail on a $350,000 bond.

He is scheduled to appear in court on August 10.
