Skai Jackson domestic violence case dismissed due to lack of evidence

Skai Jackson won’t face charges following her arrest following an argument with her boyfriend… because prosecutors say there just isn’t enough evidence to take the case to trial.

The LA County District Attorney’s Office tells TMZ … they are declining to file charges because Skai has no criminal history, the alleged victim has no injuries and he is refusing to cooperate with prosecutors.

TMZ broke the story the Disney Channel alum’s arrest …after police say she was hanging out with her boyfriend at Universal CityWalk last week.

We’re told officers responded to the scene at CityWalk and security arrested the couple after video showed Skai pushing her boyfriend.

Police say Skai and her boyfriend both denied anything physical happened — despite the video — and told officers they were happily engaged and expecting a baby.

Skai was still arrested for domestic violence, but was released only a few hours later.
