Security camera video that showed a man dropping, throwing and slinging a child outside a Riverside home led to the arrest of the boy's father, according to police.
In the video captured July 5, a man can be seen arguing with a woman identified as the man's girlfriend, according to police. He is seen holding the young child -- police said the boy is 18 months old -- and speaking to the woman before dropping him.
During the confrontation, the man appeared to swing the boy at the woman.
Police were first alerted to the video by someone who posted it to a Facebook group page. Officers searched door-to-door in the neighborhood and located the man in the Montecito Estates subdivision of the Riverwalk neighborhood in Riverside.
The child suffered non-life-threatening injuries and was treated for cuts and bruises at a hospital. He was released to his mother.

The boy's father, identified by police as 27-year-old Techoak Lim, was arrested on suspicion of felony child endangerment. NBC4 is attempting to confirm whether he has an attorney.
Police said the mother and father are separated and share custody of the child. The woman seen in the video is not the mother of the child.
