(AP) — A Lincoln man has been arrested on suspicion of severally beating his 5-month-old son.

The Lincoln Police Department says 43-year-old Raad Al-Masaudi was taken into custody Wednesday. He faces felony counts of child abuse and serious bodily harm.

Al-Masaudi told the boy’s mother while she was out grocery shopping on Nov. 12 that the boy’s toddler sister head-butted the infant. Al-Masaudi says he tried CPR on the boy, who had gone limp and was not breathing.

The parents took the infant to the hospital. Police say Al-Masaudi’s account was not consistent with the boy’s multiple brain bleeds.

Al-Masaudi is at the Lancaster County jail. Court records do not list an attorney.

The boy remains hospitalized in critical condition.
