The six-year-old son of US rapper Flo Rida is in intensive care after falling from a fifth-storey apartment window, according to legal documents filed by the boy's mother.

Zohar Dillard fell out of the window on to hard concrete on 4 March 2023, according to a lawsuit his mother, Alexis Adams, filed in New Jersey Superior Court.

Ms Adams is suing her landlord, alleging the accident followed multiple complaints about faulty window guards.

The suit alleges that Zohar "suffered severe and permanent injuries" that will affect his ability to perform "his usual functions" in the future.

His serious injuries include multiple pelvis fractures, left metatarsal fractures, grade three liver laceration, internal bleeding and collapsed lungs.

Ms Adams' lawyer Steven P Haddad said Zohar remains in a full body cast at the hospital, and it is unclear when he will be able to return home.

In a statement shared with local outlet News 12 New Jersey, Adams said it has been devastating to watch her son go through such "pain and trauma" that could have been prevented.

She went on: "As a single mum to a special needs child this feels like a nightmare. My heart is broken into a million pieces.

"I am devastated, angry and struggling to come to terms with the fact that my only child has suffered severe injuries due to the wilful negligence of our landlord and others involved in failing to take necessary safety measures."

Zohar has hydrocephalus, a neurological condition caused by a build-up of excess fluid in the brain.

Adams alleges that she had filed multiple requests with her landlord for adequate window guards for her Jersey City apartment.

One of the defendants named in her suit, Pitch Perfect 74 LLC, did not have contact information listed in public records, according to NBC News.

Goldberg Management, a real estate company also named in the suit, did not immediately respond to NBC's request for comment.

A best-selling music artist, Flo Rida, Zohar Dillard's father, has hits including Right Round, Low and Wild Ones.
